The very first glasshouses were not entirely made of glass. That is, their construction did not entail four walls that consisted primarily of glass. But they were surprisingly large, and designed for a specific purpose—the storage of container-grown citrus trees in winter. In Italy these “limonaia” (related to the “orangerie” later developed in France) had […]

Walking into any well-stocked GLASSHOUSE feels like stepping into a world of green. Quickly, your eye will pick out the exceptions to that green — pink orchids, red begonias. But the green background is what provides the overall sense of life in the greenhouse and makes the colors stand out. The same applies in a […]

Dan Hinkley’s suggestions turn gardeners into plant hunters  Any plant Dan Hinkley likes, I want. And I’m not alone. When this world-class plant explorer spoke at the Northwest Flower & Garden Show on “Dan Hinkley’s Favorite 25 Plants,” the room was packed. As he reeled off the names of his choices, Dan never outlined cultivation […]

A greenhouse can be an ideal place to force daffodils into bloom in early spring. If the bulbs have been potted in fall and kept in a place that is cold but not freezing, they will have gotten the 12 to 14 weeks of chilling they need. Now they can be brought into the warmth […]

As part of an annual tradition at Smith College, in Northampton, Massachusetts, rooted ivy cuttings are distributed to each incoming first year student–just one indicator of the botanic leanings of this prestigious women’s college. With late winter’s days lengthening, Smith’s Lyman Conservatory– one of the few remaining plant conservatories in the United States built in […]

With trees, size matters. Sometimes towering behemoths block light to gardens and greenhouses. Pruning with a chainsaw may be the only option. Or sometimes a lack of trees results in homes and outbuildings bereft of unifying plantings.  In both cases, the best garden design strategy—plant the right-sized trees now. I talked with Nancy Buley, Communications […]

It may be cold and bleak outdoors, but this is definitely a time of year when it’s easy to appreciate the advantages of greenhouse gardening. Just take your cue from the Conservatory of Wave Hill, a public garden located in the Bronx, New York. Here, the fragrances and colors of other climes help us momentarily […]

It’s indoor seed sowing time! Whether you set up a small table, or a full-size greenhouse, seed starting can sometimes be fraught with challenges. Just when you think your seedlings are growing well, they can turn up their toes. It all comes down to the fungus among us, says Rose Marie Nichols-McGee, president of Nichols […]

Recent years have seen renewed interest in vegetable gardening everywhere, but perhaps nowhere is this more pronounced than inside our larger cities. Despite the challenge of growing in the densely populated confines of city spaces—and subject to the often intense growing conditions within these microclimates, some New York City gardeners appear to embrace their limitations.

The first time I tramped a trail in a Costa Rican rain forest, while being buzzed by hummingbirds as thick as mosquitoes in Michigan, I looked at a vine clambering over a nearby tree and realized: Hey, that’s a philodendron. It was the same plant with heart-shaped leaves that can be found in greenhouses, fern […]
