The Green Light

George Ball is chairman of W. Atlee Burpee Company and past president of The American Horticultural Society.


Welcome to the first day of summer, the summer solstice, when the sun is at its highest, vegetation greenest, daylength longest, and night shortest. Call it, “summer cum laude”, since we’re so happy that our year’s longest day has come.


We edge downslope now to December’s winter solstice. From today onward, daylight will progressively shorten, and nights lengthen. Ripening plants need less sunlight; night temperatures come into greater play. The plant’s growth is less urgent than its fruiting—tomorrow slowly begin the more temperate nights of harvest time. Watch for evening mists to rise from pastures, lawns and gardens.


Mid-March’s spring equinox coincided with the imposition of safety measures to guard against the COVID-19 virus. As a rule, we regard our residence as a refuge. Since the Great American Lockdown it has felt at times like house arrest. Yet spring gradually released its light on innumerable young leaves, shoots, buds, and sprouts. The sun has revealed everything living around us morning, noon, and evening. Green light seems to wash over everything and everyone.


Parents and their offspring have found inspiration and liberation in the backyard. They bask in warm weather, get their fill of chlorophyll, and care for new gardens. After all the TV binge-watching and telecommunication screen time, three dimensions seem strikingly innovative, and the colors so lifelike. We’ve rediscovered and, in some cases discovered, our yards, parks, and forests.


Though green is not a primary color like red, blue, or yellow, it is the primal color of our world—resonating with beauty, nourishment, and life, the one thing we can’t live without.


The vibrant tones of plants and trees comprise the green of greens, the wavelength of light to which our eyes are most responsive. Green excites our visual apparatus and stimulates our neurons like no other color.


Vegetation is the bridge between Earth’s terrestrial biosphere and its atmosphere— a massive relay station that captures sunlight and, through the marvel of photosynthesis, converts it into chemical energy that fuels plant growth and reproduction and, by extension, nearly 8 billion humans and all other life on the planet. No green, no oxygen, no life, no us.


Green rules the world. Research gleaned from satellites has established that plants are the predominant lifeform of our planet’s biosphere, representing 81% of Earth’s total biomass of 550 gigatons (550 billion tons) of carbon. The nearest contenders are bacteria (about 13 percent) and fungi (22 percent). Human biomass is .01 percent, cheek by jowl with termites and krill. Cheer up; as consumers of earthly life, humans are unsurpassed.


For aeons, plant life has been under siege from a ravenous horde of herbivorous predators, from beetles to elephants, that would consume every snackable bit of green foliage, and destroy all life on Earth.


For each species of green plant, there are five species of animals. Of the 6,836,330 animal species, 30% are straight-up herbivores, and 40% omnivores who dine on both vegetables and animals. Preventing a “plantaclysm” are carnivores (30%) that prey on herbivores and omnivores, reducing their numbers so plants and trees can thrive and survive. Carnivores keep the planet green.


The pandemic that shuttered us indoors has serendipitously opened our eyes to the green realm right outside our house, a new kind of living room, where, while we tend our plants, we are productive citizens of the all-encompassing empire of green.

Remembering Betty Scholtz and Linda Yang

The Board of Directors and Staff of The Horticultural Society of New York mourn the death of two of our longtime supporters, Elizabeth ‘Betty’ Scholtz and Linda Yang. Betty was a dedicated Trustee for many years and continued her involvement with The Hort as an Advisory Board Member. In 2009, we honored Betty at our Annual Fall Luncheon. Linda Yang was on our Library Committee for many years, and was a regular supporter of the Flower Show and the library. We send our condolences to their family and friends. Both extraordinary women will be greatly missed.

COVID-19 Update, Site Closures, and Emergency Fundraising

We hope this message finds you, your family, and loved ones safe during this extremely difficult time.

Due to COVID-19, all Hort public and educational programs will remain closed until further notice. This includes: school-based programs, public programming at The Greenhouse Education Center at Denny Farrell Riverbank State Park, workshops at seniors centers, public green-space activities, and our therapeutic horticulture program on Rikers Island.

Our main office is also closed. Everyone at The Hort has been working diligently with our partners – including nonprofits, city agencies, and state agencies – to adjust to the crisis, make the proper arrangements, and plan to resume full operations when it is safe to do so. Staff are currently working from home and available to assist you by email. Please write if you have a question and do not have a direct contact.

With that said, in the long-term not being able to provide services will jeopardize direct revenue vital to the organization’s finances. This crisis also prevents us from holding our Annual Spring Fundraising Event.

That is why your support now is absolutely crucial. During this crisis, 100% of your donation will go towards protecting the jobs of our program staff and helping us avoid layoffs. After the crisis, it will allow us to rebuild our public school and horticultural therapy programs, restoring a sense of normalcy to thousands of New Yorkers across the city.

Our staff and the communities we serve across NYC thank you in advance for your support in these turbulent times. With yo12ur participation, The Hort can continue to provide vital services and help New York heal in the months and years to come. Please visit our donation to lend us your support:

This Sun is Our Sun

George Ball is chairman of W. Atlee Burpee Company and past president of The American Horticultural Society, Washington, D.C.


Today at noon, unplug your backlit screen, stroll outdoors and take in the buoyant charm of reflected light. Afterwards, take a few minutes to reflect on the sun, the superstar powering the existence of the earth—including us, all things animate and inanimate, everything.


The Vernal Equinox is the first day of spring, the occasion par excellence for honoring the sun, and every gardener’s unofficial national holiday. From our earthbound vantage point, the equinox feels like the solar system’s yearly reboot: calibrating the seasons, hours and minutes, nights and days, the season ahead, and the circadian clocks that tell our minds and bodies what time it is.


From today forward, the sun will arc ever higher over the earth, reaching its peak on the Summer Solstice, the first day of summer. In the coming months, we can bask in the prospect of more sunlight and heat, longer days and shorter nights, and a thriving solar-powered landscape, exploding with life, color, aroma, and abundance.


NASA’s dazzling new images of the sun, taken by the Parker Solar Probe, bring us ever closer to our neighborhood star. The solar close-ups, taken from a spacecraft the size of a compact car about 4 million miles from the sun’s surface, are the closest so far. However, the luminous images of roiling gases fall short of bringing the sun back home. Instead, they remind us of the sun’s utter singularity, unfathomable heat, and daunting remoteness, just short of 93 million miles.


Back here on earth, there is something new under the sun: a humanmade sun in the making. A consortium of 35 nations is collaborating to create the first humanmade star on Planet Earth, sited on 444 acres in a small town (pop. 1,000) in southern France. Scheduled for completion in 2025, the megaproject, the most massive scientific research undertaking in history, will be the most expensive structure in the world. Think big.


The mini-mini-miniature new-fangled star (named ITER, aka International Thermonuclear Experimental Reactor) will allow earthling scientists to recreate the forces powering the sun and distant stars. The goal is to determine if nuclear fusion—not to be confused with nuclear fission—can safely serve as a carbon-free and inexhaustible source of energy for the world. Let’s hope so.


As of February 4th, the new star’s site incorporates a sculpture, Sans Titre, (Untitled), by American artist Christine Corday, that fuses humanity’s creative and scientific aspirations. A fully functional, nickel copper alloy, five-pound bolt, it will join uncountable others keeping the mega-station together. The untitled work, likewise unidentifiable, will be an invisible collaborator, both participant and witness to the world’s most gigantic spectacle of all time. Its humility and untitled title remind us of the nameless craftspeople who erected the megalithic structures, pyramids, cathedrals and other glories of human endeavor.


A new, humanmade sun is an inviting prospect. The original sun, one of the more than 350 billion stars in the Milky Way, has been with us a while, debuting 4.6 billion years ago. Equal in mass to 109 Earths set side by side—it cannot readily be shoehorned into a medieval village in southern France. This new, compact model is a development to be celebrated around the world.


If you wish to bring a star to your home, there’s no better place to start than a garden. Step outside to experience the sun in all its power, glory, and majesty. In your garden, you can marvel at the miracle of photosynthesis, the miraculous conjunction of sunlight, water and carbon dioxide that creates the sugars that engender plant life, and, for that matter, all life.


Your home’s solar laboratory offers a season of delectable and beauteous discoveries that you can see, touch, smell, and taste—all sponsored by the sun, our local star.

Six Plants and Flowers That Will Attract More Hummingbirds to Your Garden

Jenn Sinrich


Hummingbirds might be tiny, but they have hearty appetites and get their fill from a myriad of plant species found in gardens. In fact, it is thought that many plants, particularly the narrow and tubular varieties, have evolved over time to accommodate their long, slender bills. “Some flowers are so narrow they can only be pollinated by hummingbirds!” says Paddy Cunningham, birding expert at Bonnet House Museum & Gardens in Fort Lauderdale, Florida.

If you’re looking to attract these small but wondrous birds to your garden, there are several basic elements you should include. Firstly, you must have some trees, shrubs, or vines nearby to create shelter and a sense of security, according to George Pisegna, Deputy Director and Chief of Horticulture at The Horticultural Society of New York in Manhattan. “The garden needs to have enough open space for the hummingbird to navigate from flower to flower, have brightly colored flowers (particularly red) that are tubular, and water, as hummingbirds love a gentle, continuous spray.” To help guide you cultivate your own hummingbird oasis, here are the garden plants they love best, according to our experts.

This bold and colorful flower is known for its trumpet-like shape, which comes in handy for hummingbirds as it allows them to reach the inside nectar more easily. This flower thrives in spring and fall, according to Lowe’s live nursery expert, Lester Poole, and grow best in areas that receive at least six hours of direct sunlight.


“This perennial is a cheerful plant with clover-shaped foliage and thin, airy, tubular stems,” shares Valerie Ghitelman, Vice President of Product Development and Design, “Its flowers bloom in a wide range of colors such as red, yellow, white, blue, lavender, pink, and salmon.” Hummingbirds tend to love columbines because they stick around—they’re drought resistant and don’t require much water.


You’re probably most familiar with this plant for its use in the kitchen. Its family contains mints, basil, and salvias in a tremendous array of sizes and colors. “All provide long-lasting nectar sources, and by staggering the annual forms and the perennial forms you can have season-long nectar sources,” says Poole. “Pineapple sage is a super source for hummingbirds, with large quantities of scarlet, tube-like blossoms throughout the summer and fall.”


This tubular flower comes in a variety of colors, most often yellow and purple. Because they are not likely to be grazed upon, they are left untouched for the hummingbird. “Lantanas are not only a three-toned showstopper, they’re able to survive period of limited water supply making them extremely easy to care for,” says Poole. “Lantanas are best suited for planting in warmer climates, as they grow best in hot, dry weather with a minimum of six hours of direct sun.”


Also a tubular flower, hummingbirds are attracted to the honeysuckle for their sweet nectar, as it name suggests. “Hummingbirds adore these open-mouthed florals and are even more attracted to their bright red toned petals, which flower on and off throughout the year,” says Poole. “These flowers prefer full, direct sun and grow extremely fast.”


These gorgeous bedding plants are fairly inexpensive, but can produce numerous flowers in a variety of colors and sizes for a few years, according to Cunningham. “Pentas have almost continuous blooms and can be used to edge beds in the smaller varieties or small bushes in the larger varieties,” she says. “They can also be put into pots and hanging baskets for balconies and porches to attract hummingbirds.”

Plant of the month: Blue Agave

Blue agave, or Agave Americana, is native to the hot, arid regions of northern and central Mexico, and some parts of the Southwestern United States. Agave plants can reach a height of 6 to 8 feet, and can grow just as wide, making them a popular statement piece in landscaping. Agave Americana is a known as the “century plant” – some species of this succulent genus take 100 years to flower in the wild, but most flower between 10 and 15 years of age. When an agave plant reaches maturity, it produces a flower stalk that can reach up to 20 feet high and bears green and yellow flowers. Once the plant flowers, it usually dies shortly afterward. The number of years before flowering depends on the vigor of the individual plant, the richness of the soil, and the climate.

Blue agave plants are deer resistant, drought tolerant, and can easily live all year round with little maintenance in warm climates. In addition to being used in the production of sweeteners and tequila, blue agave are used to produce rope and bio-fuel.

The leaves of the blue agave have extremely sharp, long, spines at the tip, which gives it an effective defense against animal predators. However, if you want to plant this striking agave in your home, it should be planted a good distance away from where anyone, particularly pets and children, could brush up against it. Once the plant has matured and flowered, it is common to see multiple “pups” around the base of the parent plant. Once the parent plant has died, it can be removed and the pups can be transplanted to start a new life cycle.

Asparagus Lemon Pasta

Here’s a quick recipe for weeknights that takes advantage of the vibrant colors and bright flavors of the spring season. For freshest asparagus, select spears with the tips tightly closed. Save the woody ends of the asparagus in a plastic bag in your freezer until you have enough vegetable scraps to make a stock; use stock throughout the spring when making rich risotto or creamy asparagus soup.

Yield: 4 servings

1 ½ pounds asparagus, ends trimmed (if you bend the stalk near the bottom, it will naturally break between the woody base and the delicate, edible stalk), and   slice the asparagus on the diagonal at approximately 2-inch intervals.

1 pound farfalle (bow-tie) pasta

3 tablespoons butter

¾ cup heavy cream

3 tablespoons grated lemon zest (from approximately 3 large lemons)

¼ cup fresh lemon juice

Kosher salt

1/3 cup fresh parsley, finely chopped

½ to ¾ cup freshly grated Parmesan cheese, for garnish

  1. Bring about two inches of water to a boil in a large stockpot with a steamer insert. Place cleaned, trimmed 2-inch pieces of asparagus in steamer basket and cook, covered for approximately 3 minutes; asparagus should be crisp-tender. Drain asparagus and rinse under cold water to halt cooking.
  2. While pasta is cooking, heat butter until melted over medium-low heat in a heavy skillet. Add cream and stir in salt, lemon zest and juice. Cover skillet and remove from heat.
  3. Cook pasta in boiling water according to package instructions until al dente. Take approximately ¼ cup of pasta water and add to sauce; drain pasta and set aside.
  4. Add pasta and asparagus to sauce and turn heat to medium, tossing and adding parsley, salt and pepper (to taste), until all is coated.
  5. Serve with grated Parmesan on the side.

Springtime Strawberry Lemonade

2 cups freshly squeezed lemon (approximately 9 large lemons)

1 ¼ to 1 ½ cups superfine sugar (you may make this by blending regular cane sugar in a food processor for a few minutes)

3 cups water at room temperature

5 cups chilled water

2 to 3 cups strawberries, cleaned and hulled then pulsed in a food processor or blender with a couple of tablespoons of water until smooth

Sprigs of lavender, mint or thyme


  1. To get the maximum amount of juice from the lemons, roll them on a hard surface before cutting in half. Slice each fruit in half and extract the juice using a juicer (manual or electric) or even your hands. If using your hands, squeeze juice over a strainer to capture any seeds.
  2. Add three (3) cups room temperature water and sugar to a pitcher with a tight-fitting lid. Shake until sugar is dissolved and water is clear, approximately 30 seconds.
  3. Add lemon juice and strawberry puree, careful to not include any lemon seeds. Add chilled water and shake, or use a large spoon to thoroughly mix. Refrigerate. Serve over ice with a sprig of lavender, mint or thyme.

Plant of the month: Jade

Jade, or Crassula ovata, are popular houseplants worldwide due to the low level of maintenance required. Jade plants are succulents – they require very little water to thrive, and can survive in most indoor conditions. Healthy plants will live for a very long time, and can survive long periods of drought due to its ability to store water in its leaves, stems, and roots. Jade is native to South Africa, and can grow up to six feet tall.

In some parts of the world, jade plants are associated with financial luck, earning the nicknames “money plant” and “luck plant.” The jade plant is also known for its ease of propagation – plants will readily propagate with high success rates from both clippings and fallen leaves. In the wild, propagation from fallen branches is the jade plant’s primary form of reproduction. Jade plants have small pink and white flowers that bloom in the springtime, but may not appear on plants kept indoors.

Spring Frittata with Feta and Ramps

Ramps are wild, and now well-known at most farmers’ markets. They look like very skinny scallions but have a stronger, garlic-like taste. They start showing up at markets in early spring. Without ramps, substitute about half the amount in scallions, plus a small garlic clove, well minced.

Yield: 4 to 6 as an appetizer; lunch for 2-4

  • Extra virgin olive oil
  • About 10 ramps, or a bunch, cleaned and chopped, including some of the green leaves (substitute spring/green onions, a few tender scapes, or a couple of shallots, finely chopped)
  • Salt and freshly ground black pepper
  • 6-7 large eggs
  • 1/3 cup feta cheese, crumbled
  • Sprinkling of chopped parsley or chives

Preheat broiler. In a medium (8-9 inch) ovenproof skillet (preferably cast iron), heat about 2 tablespoons of olive oil over medium flame. Add the ramps and sauté until tender and fragrant, about 4 minutes. Season with salt and black pepper. Remove to a bowl and set aside. In a small bowl, add the eggs and beat lightly to blend.

Set skillet over medium heat and add enough olive oil to coat the skillet well. After a few seconds, add the egg mixture, shaking the pan a bit to make sure, it spreads out evenly, and return the sautéed vegetables to the skillet. Let cook undisturbed until you see it is starting to brown lightly at the edges, about a minute. Shake the pan to see if the frittata mixture is loose. If not, let it cook a few seconds longer. Don’t stir, just let the bottom set and even brown a bit. When the top is just starting to set (that is, it doesn’t look totally runny anymore), take the pan off the burner and stick it in a hot oven (or under the broiler, but watch it closely so it doesn’t burn). Cook another 5 minutes or so until the top begins to brown. If you don’t have an oven, you can flip it and cook the top in the skillet. The easiest way is to slide the frittata onto a plate, put another plate upside down on top, flip it all over, then slide it back into the hot pan.

To serve as an antipasto, cut into thin pie-shaped wedges and arrange on a serving platter. For a lunch dish, slide each frittata slice onto a plate and serve with a green salad.

Maple Vinaigrette with Dandelion Greens

Note: Dandelion greens can be foraged, however make sure you clean well and rinse a few times before using. Many supermarkets also carry them in the produce section. You may also substitute other greens like spinach and arugula.


  • 3 Tablespoons maple syrup
  • 3 Tablespoons cider vinegar
  • 6 Tablespoons olive oil
  • ½ teaspoon Dijon mustard
  • 2 Tablespoons minced shallots (optional)
  • dash salt and pepper


  • 5-6 cups dandelion greens (or substitute other greens, like arugula and baby spinach)
  • Approximately 1 cup (or 1 bunch) spring radishes, thinly sliced
    2-3 scallions or green onions, sliced

Combine all dressing ingredients in a jar with a tight-fitting lid; shake well. Dress salad in a large bowl and serve.
