Tip of the Week: Herbal Delights

Posted in Gardening Tips on July 20 2009, by Sonia Uyterhoeven

Sonia Uyterhoeven is Gardener for Public Education. Join her each weekend for home gardening demonstrations on a variety of topics in the Home Gardening Center.

The rule of thumb with most herbs is the more you neglect them the better they grow. Most people kill their herbs with kindness by over-watering and over-fertilizing them. If you care too much for your herbs, you will only end up with powdery mildew and rotting leaves.

Herbs generally thrive in well-drained soil and full sun. The only work they require is for you to pinch them back so that they don’t get leggy and go to flower. The handfuls left from pinching back can go straight from the garden into the kitchen.

While most herbs prefer a sunny site to grow in, some herbs thrive in a slightly shady spot. Some candidates for afternoon shade are parsley (Petroselinum), mints (Mentha), lemon balm (Melissa), and tarragon (Artemisia dracunculus).

Cilantro (Coriandrum), chervil (Anthriscus), and dill (Anethum) are short-lived annuals. They go to seed after a few weeks, so multiple sowings a few weeks apart will ensure a good supply. They prefer the cooler seasons of spring and fall.

Tropical Fruits, Roots, Shoots Filled with Drama and Surprises

Posted in Exhibitions, The Edible Garden on July 17 2009, by Plant Talk

Gregory Long is President and CEO of The New York Botanical Garden.

Tropical Fruits, Roots, ShootsThe Edible Garden is meant to inspire visitors and to teach them about growing great food. One of the 11 exhibits featured in the summer-long celebration, Tropical Fruits, Roots, and Shoots in the Enid A. Haupt Conservatory, not only delivers on both counts but is a real showstopper as well, with more than 280 tropical plants and fruit-bearing trees, and dozens in flower or fruit right now.

Francisca Coelho, Senior Curator and Associate Vice President for Glasshouses and Exhibitions, has outdone herself with this tropical edibles exhibit, which features lush, elaborate displays of rare and beautiful vegetation, including everyday favorites like coffee, coconut, and cinnamon growing alongside more unusual fare like passion fruit, tamarind, and açai.

sweet pepperFran presents a global as well as a personal view of foods. You can see and learn about some of the world’s basic food crops such as rice, corn, and sorghum—staples many people have never seen in their plant form—as well as witness 42 kinds of hot peppers, Capsicum (and a handful of sweet varieties). Fran grew up eating food accented with peppers in her native Trinidad. In the Caribbean, peppers are showy and spicy, and the same plant can produce fruits of widely divergent colors. For instance, the Bolivian rainbow pepper starts off purple and then turns yellow and then orange and then red. “Green and red peppers are pretty boring. Gardeners should go for a variety on both color and taste,” Fran says. Some of her favorite recipes utilizing peppers are posted on our Edible Garden Web pages.

coconut palmWhile the exhibit features plants that have edible parts, many more plants beyond peppers are ornamental. Gardeners have manipulated edible plants over the centuries to hybridize ornamentals. Fran notes: “When we garden in the Caribbean, we stick ornamentals among the food plants.” Purple seems to be an attention-getting, commanding, vibrant color with the most captivating foliage. Cordyline fruticosa ‘Negri’, the ti (pronounced “tie”) plant has deep purple, almost black, leaves. It is often used as a border plant in the Caribbean and is also used in cooking: food is wrapped in the large, thin leaves and dropped into a broth, stew, or soup. Other ornamental food plants include the grain amaranth (Amaranthus), which was used by Aztecs as cereal, and shiso (Perilla), with its deep purple, fluted, undulating leaves, used as a seasoning and as a tea.

The biggest surprises? The cashew (Anacardium occidentale), which comes from the same plant family as poison ivy and mango. Wrapped in a poisonous seed coat to protect against nature’s predators, the cashew nut is found at the end of a fleshy, flashy, bright-red fruit. And the ice cream bean (Inga jinicuil), which has a seed that when mature is fat and filled with a creamy pulp that tastes like vanilla ice cream.

You must come visit The Edible Garden and Fruits, Roots, and Shoots to see for yourself. I believe there has never before been such a display on such a scale.

Beginner’s Vegetable Garden Shows You How to Grow

Posted in Exhibitions, The Edible Garden on July 16 2009, by Plant Talk

Kristin Schleiter is Curator of Outdoor Gardens and Herbaceous Collections.

BVGHave you been toying with the idea of starting a vegetable garden but you aren’t sure just how to do it? The Beginner’s Vegetable Garden, across from the Ruth Rea Howell Family Garden, is the perfect place to learn the basics. We planted popular vegetable varieties like ‘Early Girl’ tomatoes and jalapeno peppers in simple raised beds that receive sun all day long. We used a number of different easy-to-find support structures to give you ideas that you might want to try at home.

We are growing cucumbers on a frame, a large square grid of heavy gauge wire that is propped up on one side. The frame allows the cucumbers to hang down freely from the vines ensuring perfectly shaped vegetables. It also increases air circulation around the plant, which helps to minimize diseases like mildew. Cucumbers and squash both can take up a lot of real estate, so if you have limited space, this frame lets you grow them and still have room for other plants in the garden.

Pole bean seeds are planted at the base of bean towers and spirals, which will offer the plants strong support so they can grow tall, which allows for an easy harvest while again ensuring good air circulation. When your beans reach the top of their support, snip off the growing tip to encourage the plant to produce side branches. It is best not to work around bean plants or to pick beans when they are wet to prevent the spread of disease.

Going Vintage: Heirloom Veggies in Demand

Posted in Shop/Book Reviews, The Edible Garden on July 15 2009, by Plant Talk

Richard Pickett is Director of Retail Operations.

At your next family reunion picnic you may run into some long lost relatives. Perhaps you’d think distant cousins, twice removed on your mother’s side, but in fact Lazy Housewife, Radiator Charlie, and Collective Farm Woman are beans, tomatoes and melons, respectively, more likely to be found on your plate next to grandma’s famous potato salad than out back bobbing for apples or spitting watermelon seeds.

By definition, heirloom vegetables are vintage varieties that have been preserved by passing seeds down from generation to generation. Heirlooms have often been selected for taste, appearance, and eating quality, and the demand for heirloom vegetables is rapidly increasing, especially among gardeners looking for unique flavors and freshness. While many heirloom vegetables are now available at farm stands, varieties of tomatoes, beans, and cucumbers are the most popular.

Among edible heirlooms literally thousands of varieties are available, many handed down, others swapped with fellow gardeners, and a growing number purchased from the ever-expanding selection of specialty seed purveyors. For The Edible Garden, the Home Gardening Center’s Lois Loeb Vegetable Garden has been redesigned by Rosalind Creasy into New York’s best heirloom vegetable garden. Using seeds from Seed Savers Exchange, this garden features a bountiful array of beautiful and delicious heirloom vegetables, herbs, and edible flowers. Seed Savers Exchange is the foremost organization dedicated to preserving agricultural diversity through the preservation and sharing of heirloom seeds.

At Shop in the Garden, we offer a wide variety of heirloom seeds, exclusively from Seed Savers Exchange, as well a great selection of heirloom tomato, pepper, and eggplant seedlings. You can also find fabulous garden gear online. So whether you are a longtime heirloom vegetable advocate (and there are many) or simply a home gardener looking for more variety, flavor, and excitement in your harvest basket, give heirloom vegetables a try. Who knows, in our hectic day-to-day existence, it may just be time to find the Lazy Housewife in all of us.

Gallery Talk Focuses on Squashes

Posted in Programs and Events, Science on July 14 2009, by Plant Talk

NYBG Farmer's Market - SquashThe edible squashes have been a staple food in the Western Hemisphere for more than 5,000 years. The Aztecs and Mayas, as well as the Native Americans who met the Pilgrims, depended upon the squashes as one of the “three sisters” (corn, beans, squash) of early agriculture in the Americas.

Though squashes come in an amazing variety—from tender summer zucchini to hearty acorn squash and pumpkins—their great diversity comprises only five species: Cucurbita argyrosperma, Cucurbita ficifolia, Cucurbita maxima, Cucurbita moschata, and Cucurbita pepo. (Bottle gourds, thought by Swedish botanist Carl Linnaeus to belong to Cucurbita, are now placed in a separate genus, Lagenaria. They are useful for a variety of utensils and handicrafts, although not as good for eating.)

The domesticated species of Cucurbita were all derived from different wild ancestors—wild species that have survived droughts, pests, and diseases without care from people. Although the wild ancestors bear small, hard, bitter fruits, they are very valuable for breeding disease resistance into modern food plants.

Thomas Andres, co-founder of The Cucurbit Network and an Honorary Research Associate at the Botanical Garden, has worked for 30 years with Garden scientist Michael Nee, Ph.D., on squash research. Andres will present a Gallery Talk in the Britton Science Rotunda and Gallery on Friday, July 17, at 2 p.m. about his beloved topic. Following his talk is a behind-the-scenes tour of the William and Lynda Steere Herbarium to see how scientists identify and classify plants and to view some specimens of squashes and their relatives.

Space is limited, please call 718-817-8703 for reservations.

Tip of the Week: Vertical Gardening

Posted in Gardening Tips on July 13 2009, by Sonia Uyterhoeven

Sonia Uyterhoeven is Gardener for Public Education. Join her each weekend for home gardening demonstrations on a variety of topics in the Home Gardening Center.

The best way to handle life’s ups and downs is to make a commitment to vertical gardening. I have, and it has always led me to new ideas and creative ways of growing my vegetables. Why garden vertically? With an annual vine, a clematis, or a climbing rose, it seems pretty obvious. So why not, then, bring this gardening technique into your vegetable garden?

Saving space is an obvious reason for growing vertically, but vertical crops are also easier to harvest and are less susceptible to diseases. The crop is lifted from its usual place on the ground where it fights for sunlight and good air circulation. I notice a big different in my cucumbers when I grow them up a tepee or a trellis versus letting them sprawl on the ground. 

This year I will be experimenting with A-frames that have a grid or wire mesh on either one or both sides. I will be growing cucumbers up these structures, but I could just as well be trying melons, squashes, gourds, or tomatoes. (If you are growing a vegetable that will eventually produce heavy fruit, give the fruit extra support by either cradling them with an old pair of panty hose or a nylon or mesh support.)

I am more of a practical woman. What I like so much about these vertical frames is that there is space underneath that can be used to plant lettuce, beets, or any fast-growing crop that will capitalize on the good light while the vine is young and then adapt graciously to the part-shade that the vine eventually casts.

Plan Your Weekend: Gardening in Tough Times

Posted in Exhibitions on July 10 2009, by Plant Talk

Jane Dorfman is Reference Librarian/Exhibitions Coordinator in the LuEsther T. Mertz Library.

Garden trends come and go, but the edible garden, despite its changing names, has been a stable feature in American life.

Mickey-Mouse-Green-Thumb-Contest-Poster--3This summer, in conjunction with The Edible Garden summer-long exhibitions, the LuEsther T. Mertz Library presents a display featuring the “war” or “victory” garden, the movement inspired during the years of World War I (1917–18) and World War II (1941–45) when vegetable gardening became an act of patriotism as well as practicality. Citizens were encouraged to grow, can, and store crops to ensure self-sufficiency at home and to keep the nation’s distribution of food focused on our troops and allies.

On display are brochures, photos, nursery seed catalogs, a musical score, and archival items that narrate and depict the Victory Garden movement that spanned the nation and, with government, business and community support, proved to be successful. One poster circa 1944 features Mickey Mouse pitching the Green Thumb Contest sponsored by the National Victory Garden Institute. From 1942 is a musical score, Swing that Hoe and Watch Your Garden Grow, by William Eben Tourjee.

The exhibit also highlights The New York Botanical Garden’s significant contribution to the national cause during the years of the Second World War, including images of the Garden’s own Victory Garden.

Summer School: At the Beach or at the Garden

Posted in Learning Experiences on July 9 2009, by Plant Talk

Take Classes in Amagansett, Learn Veggie Gardening, and More!

Duncan Himmelman, Ph.D., is Program Manager for Continuing Education.

I decided to take advanced physics in the months between my junior and senior years in high school, sensing it would give me a slight edge in the college application process and that it would free up my senior year schedule to pursue extracurricular activities. My friends were aghast: “Nerd” had not yet been coined, but I was certainly viewed as the precursor. Yes, it was difficult, both the advanced physics and loss of fun times with friends and family, but it was taught in such an engaging manner that it galvanized my decision to pursue science in college. Summer school was the key to my future! Who knew?

Summer is the ideal time to take on an academic or leisure time educational pursuit. Continuing Education offers a diversity of programming this summer both here at the Garden and in such far flung places as Amagansett on Long Island. Located in the middle of summer-cottage country, the nearby beaches of Amagansett provide spectacular vistas from which to learn the fundamentals of drawing or watercolor painting. If art is not for you, then learn about garden design or growing roses using a totally organic approach. No matter what, combining the leisurely pace of summer life with a fun course or two can be just what the doctor ordered.

If you are staying closer to home, near the Garden, why not enroll in the one-day Vegetable Gardening for Beginners program on Saturday, July 18. In keeping with The Edible Garden celebration and with the current “grow your own garden” craze sweeping the nation, come get the fundamentals needed to grow a bunch of veggies, from soil preparation and seeding to garden maintenance using strictly organic methods. Summer school was never so much fun.

For those who are more serious-minded about summer school courses, consider signing up for one of the Summer Intensives offered in Botanical Art and Illustration or Floral Design. Located here at the Garden, you will be amazed at the many locations where you can gain inspiration for the Illustration courses and actually sit outdoors to draw. Floral Design, an intensive five-week program, brings you from basic floral techniques through the creative process of designing wedding and “grand scale” arrangements. Perhaps, like my physics summer school course, you’ll find it demanding, but it may also be the touchstone you’ve been waiting for!

Preserving Knowledge of Traditional Plants in Micronesia

Posted in People, Science on July 8 2009, by Plant Talk

Wayne Law, Ph.D., is a Postdoctoral Research Associate who studies ecology, ethnobotany, and conservation in Micronesia. Come speak with him at our Café Scientifique on July 9, from 6 to 8 p.m., in the Conservatory Courtyard as part of The Edible Garden.

Micronesian produceWhen someone asks you to visualize a banana, most people in the United States will picture the typical, slightly curved, yellow-skinned banana with a bland white flesh that can be found at local grocery stores. However, a number of different varieties exist: small bananas, straight bananas, red-skinned bananas, creamy-tasting bananas—even bananas that have a bright-orange flesh—and many of these varieties can be found on tiny islands in the Pacific known as Micronesia, where Botanical Garden scientists are conducting research.

One of our goals in Micronesia is to record traditional plant knowledge that is the foundation of these islands’ unique cultures. The plant knowledge throughout this region is incredibly diverse as plants are integral to all aspects of daily island life, from the construction of houses and canoes to use as medicines and foods. As traditional ways of life are influenced by modern amenities, we are constantly seeing evidence that traditional plant knowledge is being lost and that many common items once made from nature are being replaced by plastic products that have an origin thousands of miles away. One study we conducted analyzed the knowledge of food plant varieties in Kosrae, the easternmost island of the Micronesia chain.

By the early 1900s, Kosrae, an island home to 7,000 people in the Eastern part of Micronesia, had already been exposed to French and Russian explorers, whalers, beachcombers, pirates, and traders, beginning the erosion of what had been a very traditional Pacific island lifestyle. At that time, Ernst Sarfet, a German ethnographer, documented much of Kosrae’s cultural aspects and plant uses during the Hamburg South Seas expedition, an impressive voyage that lasted two years and produced a 13-volume publication based on the observations made during the expedition. The translated work provides an early record of the different varieties of bananas, breadfruit, coconuts, pandanus, sugar cane, soft and hard taro, and yams. (The photo shows a display of some of the fruits and vegetables mentioned, during a holiday celebration in Kosrae.)

Savor the Tastes of Arthur Avenue, the “Real Little Italy”

Posted in Exhibitions, The Edible Garden on July 7 2009, by Plant Talk

Carol Capobianco is Editorial Content Manager at The New York Botanical Garden.

Arthur Ave Cookbook

Arthur Avenue.

Those two words conjure up so many sights, sounds, smells, and flavors all having to do with great food—Italian, that is.

As a kid growing up in the neighborhood I remember seeing round men with a napkin about their neck dousing raw clams with hot sauce and then slurping them down. I remember hearing the cacophony of clucking, caged chickens awaiting their turn with the butcher at the fresh poultry and rabbit market.

And the smells of the beloved “real Little Italy” were overwhelming and everywhere: fresh bread from the bakeries, sausage and peppers grilling at the street feasts, and from open apartment windows, tomato sauce (or “gravy” as we called it) simmering away.

But it was the flavors—and the quality—that are most reminiscent and what still brings me and countless others back to the area. The melt-in-your-mouth ravioli and fresh mozzarella, the sharp cheeses and imported prosciutto, the fine cuts of meat and the specialty fish, the incomparable breads and pastries, the strong espresso coffee.

And for those who don’t cook or who want to taste Italian food at its best in America, there are the restaurants, with menus filled with so many delicious meals that just reading the choices makes your mouth water. When I take my first bite into a dish made at these places, I can’t help but close my eyes and sigh with appreciation for these superior, soulful foods that can be savored right here in New York—and so close to The New York Botanical Garden.

Some of these delectables will be available for you to sample this Thursday from 6 to 9 p.m. at A Taste of Arthur Avenue, the first of seven Edible Evenings planned during The Edible Garden.

If you’d like to try your own hand at cooking some of the special dishes found on Arthur Avenue, you’ll find dozens of recipes in The Arthur Avenue Cookbook carried at Shop in the Garden.
