AboutOrchids

Today’s orchid related vocabulary word is lithophyte. Pronounced “LITH-ah-fayht,” it rhymes with “lip-oh-fight.” A lithophythe is a plant that grows attached to rock. Sound like science fiction? Well, just as orchid roots can attach to tree trunks and branches, some can also attach to rocks. Lithophytes may sink their roots into crevices and […]

So many people think of orchids as delicate and fragile, but this little Sarcochilus hartmanii is one tough plant. Related to Phalaenopsis and Vanda, in the wild Sarcochilus grow as lithophytes, or rock plants. Their roots attach to cliff-face rocks in eastern Australia, holding on despite strong ocean winds. They can handle a wide range […]

It may look like just another orchid, but this blooming Epipactis gigantea is special for a few reasons. Unlike most commonly cultivated orchids, which come from tropical regions, this orchid is a San Francisco native. In fact, it’s native to a wide part of western North America, spanning from SW Canada to NW Mexico, and […]

Tiny Lepanthopsis astrophora has a name that’s bigger than the plant itself. I bought this Masdevallia relative at a sale at OrchidMania last year, and it’s been in constant bloom for a year. The flowers only last a few days each, but there’s a constant resupply.

If they look small in the pictures, they are! Each […]

Nicknamed the Hardy Chinese Orchid, Bletilla striata is a terrestrial that grows in soil. Originally from China, Japan, and Korea, Bletillas go dormant over the winter, and can handle light freezes. These flowers have been slowly opening over the past few days. They’re still not completely open in these photos, but you can see their […]

Here are some more pictures from our recent visit to Phipps Conservatory in Pittsburgh, PA.

Originally I mis-identified this orchid. Its correct name is Bifrenaria harrisoniae. The center looks like a smiley face with a fuzzy beard.

In high humidity at Phipps, orchid roots grow exposed to the open air. The roots growing around a wooden […]

It’s a sign of springtime that I have so many orchids starting to bloom. This little red Maxillaria tenuifolia may not look as impressive as larger orchids, but it packs a big scent. This single flower fills our front room with a sweet coconut aroma. It is native to Central American jungles, and enjoys warm […]

There is no simple formula for how many times a week an orchid should be watered. I give some estimates on the pages that describe orchid care for common species, but they are really meant as general guidelines, not a strict set of watering rules. You have to factor in temperature, humidity, light, […]

Spring is on the way, which means I am already busy repotting. With the season bringing stronger sunlight and more warmth, most orchids start a cycle of growth. It’s the best time to replace old potting material and provide an open, fresh environment for new roots.
Years ago, I was shocked when I first saw an […]

This beautiful Helcia sanguinolenta flower has been open for a few days. They live as epiphytes at elevations as high as 10,000 feet (3000 meters) in the Andes of Ecuador. Its native climate is similar to San Francisco’s, with mild temperatures and foggy days.
