At this time of year, one can hardly miss the grand display of yellow flowers on the floodplain of the Bronx River. The show is especially spectacular from the vantage point of the Magnolia Way bridge at the northern end of the Garden. The view is beautiful, even breathtaking.
Alas, all things are not as they seem, and the golden flowers belie a menace. Yes, beautiful, but a menace nevertheless. The profusion of yellow blooms belongs to an invasive species, Ranunculus ficaria, the Lesser Celandine. Lesser Celandine is a species of buttercup (Ranunculaceae), and is not to be confused with Celandine, a member of the Poppy Family (Papaveraceae).

It’s not always easy to see where you are going when on the proverbial “career path.” At times the path tends to be longer than expected and sometimes a bit bumpy. At age 44, I can finally look back with a bit of clarity and see how I finally made it to today.
With advanced degrees in Elementary Education, Psychology, Counseling, and Social Work, I’ve had the opportunity over the years to work with various populations, each with differing needs and more than I could adequately provide for, especially from behind a desk.
But that’s where it began for me. During counseling sessions, something would happen when we fiddled with the plant on my desk, listened to the sounds of birds, smelled the fresh air through the screen, and watched as Mother Nature danced outside the office window. I couldn’t put my finger on exactly what made it work, but I knew it did work. So I began conducting sessions outdoors in the natural world. A novel idea, I thought. I think I will call this therapeutic milieu “horticultural therapy.”
It wasn’t until I received the Continuing Education catalog that I discovered that horticultural therapy wasn’t my invention after all. How naive of me to try to take credit for a field that has been in existence since the time of Egyptian civilization.
I enrolled in Introduction to Horticultural Therapy and was led through the historical background, foundations, and applications of this field by Katherine Sabatino. An experienced horticultural therapist, she was able to take years of personal contemplation and tie it up in a nice big bow for me. My decision was made, my career path defined, with all arrows pointing toward horticultural therapy.
The instructional staff facilitated my learning process throughout the course of study. The expertise and experience of these very people are what distinguishes NYBG’s program from others.

Who’s afraid of the hemlock woolly adelgid? Certainly, many gardeners in the Northeast. Like many pests that plague us, these little creatures were introduced from abroad. In their homeland (Japan) they are kept in check by a type of ladybug that is a natural predator. Here in the United States, though, the woolly adelgid has free range. The only natural challenge it faces is extreme temperatures—once the thermometer drops below 23°F or -5°C, the mortality rate of these fluffy little critters rises.
So what is hemlock woolly adelgid and why should we be concerned? This pest spends most of its life protected under its telltale fluffy white secretion. You probably have seen it cover the branches of hemlocks. It plants itself at the base of the needles and slowly sucks the sap—and life—out of a tree. This can take anywhere from 1 to 15 years, depending on the tree and environmental situations. While many pests target unhealthy and, therefore, susceptible trees, this pest prefers healthy ones.
For those of you who have grown up on the East coast, as I have, you will appreciate the importance of the Eastern hemlock (Tsuga canadensis) in the landscape. For the homeowner, it is one of the few conifers that make an outstanding addition to a shady border. It has delicate foliage, it can withstand hard pruning, and its lower branches often reach down to the ground, creating a nice, full specimen. It is an important screening and landscape plant.
What you may not have thought about is the important role that it plays in the ecosystem. This shade-tolerant tree grows slowly into giants in the forest, creating cool, shaded areas by stream and river beds that allow many fish and aquatic invertebrates to thrive.

Expect Warblers, Wood Ducks, More on this Weekend’s Bird Walks
|Debbie Becker leads a free bird walk at the Garden every Saturday from 11 a.m. to 12:30 p.m., beginning at the Reflecting Pool in the Leon Levy Visitor Center. This weekend, she’ll also lead a walk on Sunday, same time and place.
The phoebe, spring’s harbinger, has been singing its wonderful namesake song throughout the forest. Wood thrush are chiming in along with white-throated sparrows, tufted titmice, and cardinals.
While some birds are singing to lure a mate, some of our larger predators are already proud parents. Our red-tailed hawks appear to have one baby in their nest, built on a cliff-like shelf of the Library building. Mom and pop can be seen flying in and out with tasty morsels to feed the nestling.
Our baby great horned owls fledged their nest in the Forest. Last Saturday, only one baby was left in the nest (see photo) with Dad watching over him like a hawk (or should I say owl). The other owlet was somewhere in the Forest with Mom, learning how to fly and watching her hunt. Earlier this week, the second baby also fledged and now birders are treated to a spectacular show of watching them flap their brand-new wings and hop from branch to branch.
Warblers are beginning to invade the Garden. Some birders I know save all their vacation days for the last week of April and first week of May to look for these gems. Warblers are small, colorful birds that migrate from as far south as South America to the far northern reaches of the United States and southern Canada. Escaping predators and feeding on newly hatched insects, they travel up the eastern coast in the tens of thousands every April and May to their breeding grounds. This is the only chance each year to see these long-distance travelers in their brilliant breeding plumage, and birding NYBG gives you every opportunity to observe them. Last Saturday’s walk yielded a palm warbler, pine warbler, and yellow-rumped warbler.

This week is National Volunteer Week, and we salute The New York Botanical Garden’s more than 1,000 volunteers who serve in a variety of roles: They enhance the visitor experience as greeters and tour leaders, maintain the Garden’s 250 acres as horticultural assistants, teach plant science to visiting school groups and families, assist with clerical work, and collect data on climate change as citizen scientists, among many other duties. Last year they clocked more than 80,000 hours of service. The success of exhibitions, programs, and events is due in part to the dedication of the volunteers who respond to our numerous calls for help with a sense of responsibility and enthusiasm.
No matter your interests, skills, schedule, or age (our volunteers range from 14 to over 90), you, too, can help the Garden in its valuable work. No experience is necessary—you’ll be trained for your specific assignment. Volunteers are needed year-round and on weekends as well as weekdays. You’ll receive free parking and discounts in the Cafes, in the Shop, and for Continuing Education classes.
What inspires people to volunteer at the Garden and what rewards do they get in return?
Three of our volunteers shared their stories:
Kefah Rihan lives in the Bronx and is a ninth grader at Cardinal Spellman High School. He serves as an Explainer in the Everett Children’s Adventure Garden, which was his favorite part of the Botanical Garden when he first visited at age three. A friend told him about the Explainer program. “I remembered how fun my visit to the Garden was. I thought it would be a good opportunity to learn new things. I get the chance to teach kids about the wonders of the Garden, and I made many new friends in the process. It gives you many skills in life and can help make you a more sociable person.”
Melisande Schwartzfarb, from Suffern, New York, first visited the Botanical Garden in the late 1970s as a second-grade teacher at P.S. 9 in the Bronx. Walking through the Garden that spring day, she and the schoolchildren marveled at the beautiful blossoms and emerging flowers. “The children were so excited and expressed wonder at having nature so close to their crowded urban homes. The picture of that special day is imprinted in my mind as if it was yesterday.” After retiring in 2002 she became a docent at the Garden. “I am gaining an incredible amount of knowledge through the ongoing docent training programs, lectures, observations, and Continuing Education classes. A whole new world has opened up for me. The joy of sharing knowledge with children and adults from all over the city, state, and world is most gratifying. In volunteering, you are offering a service needed and appreciated at NYBG. You will also discover many opportunities for learning and expanding your own horizons.”
Ignatius Galgan, of the Bronx, had been retired from the New York City Police Department when his wife saw an advertisement calling for Garden volunteers. He signed up and now helps in a multitude of ways. “It’s one of the best things that I have done. If you’re retired, it beats staying at home and watching TV. If not, volunteering at the Garden on weekends is like a mini-vacation. There are so many interesting things that you can do such as becoming a docent, a Garden greeter, helping with the various exhibits throughout the year. Want to learn about plants? How about working with some of the best botanists in the world? These are just some of the things where your help is needed. The Garden relies heavily on volunteers. I couldn’t think of a more rewarding, fun, and beautiful place to volunteer.”
Volunteering at the Garden is a great way to expand your knowledge of plants, give back to your community, meet new people, and share your love of the Garden with others. To get involved, call or e-mail Jackie Martinez, Director of Volunteer Services, at 718.817.8564 or email@example.com or fill out an application at nybg.org.

As an institution devoted to the celebration of Earth’s plant life—to the beauty and diversity and ecological importance of plants, to the role that plants play in making all life on Earth possible, to the million ways plants contribute to human health and happiness—The New York Botanical Garden is dedicated to the conservation of plants and the systems on which they rely. So nowhere is the clichÃ© “every day is Earth Day” truer than here at the Garden. Our core institutional missions of education, horticulture, and science are, through the plant world, directly tied to a functioning and protected environment. This is why we strive to improve our own environmental performance (to be more sustainable, if you will) and to teach others how to do so as well.
For those who visit the Garden to enjoy, say, the Holiday Train Show or the explosion of floral magnificence known as spring or some other such event, this broader perspective can be easy to miss. For that matter, even those of us who work at the Garden can slip easily enough into our individual niches and lose sight of the Garden’s broader environmental role—that, for example, our 250 acres of gardens, forest, wetlands, and green spaces nestled into a spectacularly urban setting provide many important environmental services we don’t always think about. Or that our scientists are contributing to conservation around the world. Or that our educators are spreading the word far and wide, including to the next generation of leaders, about the importance of understanding and protecting the world in which we live.
Earth Day should remind us of all this, of the ongoing and critical relationship between each of us (as people, as institutions) and our environment. It should remind us of what we do right, where we can improve, and, not least of all, why we care. There is no better place than The New York Botanical Garden to come and renew one’s love of Mother Earth on Earth Day. The Garden—indeed, any garden—thrives in that space where the natural world of soil, water, sun, and plants intersects with the human environment. And that, from an environmental and human perspective, is the intersection that matters.
So, here at the Garden we have decided to celebrate Earth Month, to give ourselves a little more time to linger over the relationship we share with the natural world. And we invite you all to join us to hear what we have to say and to share with us your thoughts on this most important of topics.

Horticulture staff on the Outdoor Gardens crew welcome spring in the Everett Children’s Adventure Garden by dressing the five animal topiaries—three caterpillars, a ladybug, and a frog—in colorful Viola coats. The topiaries delight visitors year round but seem to bring a special joy after a long winter and before the spring bulb and flowering tree season gets into full swing.
What exactly does it take to make a caterpillar bloom? Many hands, many plants, and a lot of time.
Although it takes about seven days to plant all five forms, the process starts months in advance. During the summer, we drew designs and selected the varieties of violas to use. The staff at the Nolen Greenhouses for Living Collections started growing the plants in late fall to be in flower and ready to plant by mid-March. Turning a drawn design into a planting involves a little bit of math and a lot of eyeballing. As we do the installation, we keep track of how many plants of each variety we have and how many we have used to ensure there are enough to complete the design as planned.
Before planting, the topiaries look like soil-filled wire cages in the shape of an animal. Planting in the steel structure is pretty much like planting in the ground except that sometimes we are standing on ladders and sometimes we have to lie on our backs to plant. To achieve an instant effect, the plants are planted much closer together than they would be in the ground.
Soil knives are our tool of choice, because they are flat and narrow and cause less soil to fall out of the structure as we dig. We don’t usually need to replace the soil that falls out, because the new plants take up that space—as the plants grow, they root into the structure. Many plants are planted practically upside down in the structure. When gravity wants to pull our plants out of place, we use landscape staples to pin the root balls.
After planting is completed, areas that have lost soil are stuffed with damp sphagnum moss to keep the roots from drying out. Irrigation systems are installed inside each structure, but we water by hand right after planting and then usually on a schedule of once or twice a week to supplement the daily irrigation.
Can you guess how many violas it takes to make a caterpillar bloom? To find out the answer…
Caring for Mother Earth
Sonia Uyterhoeven is Gardener for Public Education at The New York Botanical Garden.
This week we commemorate Earth Day. Celebrate the life on this planet yourself by spending time in your garden. Forget the heavy chemicals and fertilizers. Sometimes they do have their place, but more often than not a healthy, well-maintained garden is all you need.
Here are some ways to help the planet.
- Make your own compost. With compost you will be essentially giving your garden all the nutrients it needs. Compost is basically a mix of “browns” and “greens.” Browns are lifeless, carbon-rich materials such as autumn leaves, straw, and wood chips. Greens are fresh, nitrogen-rich materials such as weeds and grass clippings. Pile up your compost so the mound is able to retain heat and moisture, allowing the composting organisms (the critters and microorganisms that break down the material) to thrive. Never place weed seeds in the pile unless you know how to heat up the pile to kill them off, otherwise you may inadvertently end up spreading them in compost around your garden. To speed up the composting process, chop the material into small pieces. Turn the pile occasionally and add water if you are going through a long, dry spell. Never introduce meat scrapes or vegetable oils into the pile; otherwise you will attract unwanted pests.
- Add aged manure to your garden. Apply it particularly around roses and in your vegetable garden to give plants a nutritional boost. You can buy either bagged manure or farm manure. If it is straight from the farm, it needs to break down for at least 3-6 months before you can safely add it to your garden. If you buy farm manure in the spring, just keep it in a pile and apply it at the end of the fall season. Many people incorporate manure into their compost to create a hearty mix.
- Use organic fertilizers. These are better for the plants and for the environment. Don’t be put off by the low numbers on the organic fertilizers—these represent the percentage of nutrients that are initially available to the plant. There are more nutrients in reserve that are bound and will slowly be released, providing a moderate and constant flow of nutrients. Inorganic fertilizers that have high numbers give the plant an abrupt blast and then it goes through withdrawal; you have created a plant junkie that suffers from a feast-or-famine syndrome. Consistency is always best for your little green friends. Take a look at the ingredients to see what is in your fertilizer: seaweed and kelp provide great micronutrients; green sand is rich in potassium; phosphate rock has good mineral content; compost and dried whey are popular organic materials.
