Office Orchids

Sunday, July 22nd, 2012

Orchids have been staples of office decor since supermarkets and garden centers began selling mass-produced plants in the 1980’s. Tough, modern hybrids can survive, and even thrive, in work environments which often have less than ideal growing conditions. Check the following tips to keep your office orchid blooming: As always, it helps to know what […]

Mystacidium

Monday, July 9th, 2012

Mysta-what? With a name bigger than its tiny white flowers, this mini orchid doesn’t look tough. However, looks can be deceiving. Despite its delicate facade, this species survives attached to thorny Acacia trees in the heat of South Africa’s savannas, where few other orchids can live. It can also handle light winter frosts. This toughness […]

Rhynchostele

Saturday, June 23rd, 2012

If orchids could read blog posts, I might be suspicious of this Rhynchostele. I complained online that it hadn’t bloomed in 6 years, and a few days later, a pair of new flowers appeared. You can find it noted last in the list at Outdoor Orchids in San Francisco, part 1 under the name Lemboglossum. […]

Chinese Ground Orchid

Sunday, May 27th, 2012

Sure, orchids are great, but wouldn’t it be nice to just stick one in the ground like a regular plant? Well, you can do just that with the Chinese Ground Orchid, or Bletilla. If you can grow a tulip or a daffodil, you can grow a Bletilla. Resembling Cattleyas, their charming flowers have ruffly ridges […]

Late Winter Orchid Care

Saturday, March 10th, 2012

As winter winds down, it’s still the dry season in the native homes of many orchids. They often take the opportunity to flower before the wet season begins. Cattleyas, Dendrobiums, Oncidiums, and others need this dormant period to bloom. Even when dormant orchids spring into bloom, resist the urge to water more. Many dormant types, […]

Coelia

Sunday, January 15th, 2012

Coelia bella has a graceful beauty, a rich fragrance, and a musical name. Its delightful purple, white, and yellow flowers emerge like little trumpets, and have the sweet scent of marzipan or almond oil. This species is native to Mexico, Belize, Guatemala, Costa Rica, and Honduras. Coelia is easy to pronounce; just ignore the “o” […]

Hold the Ice

Wednesday, January 4th, 2012

I’ve already blogged about my objections to watering orchids with ice cubes. It doesn’t take a degree in botany to see that tropical plants, especially warm growers like the Phal in the first photo below, don’t like cold temps. But there’s another, less obvious reason why ice isn’t right for orchids — ice cubes don’t […]

Dendrobiums

Saturday, December 3rd, 2011

Dendrobiums are one of the largest and most diverse orchid families. They include more than 1200 species and thousands more hybrids, with a vast range of colors, shapes, sizes, and growing conditions. The first 2 pictures below show the most common variety, the somewhat confusingly named Phalaenopsis-type Dendrobiums. No, they’re not Phals — they’re Dendrobiums […]

Orchid Care in Winter

Saturday, November 26th, 2011

Orchid care changes with the seasons. Growers need to adjust for winter’s approach in the Northern Hemisphere. Orchids with pseudobulbs are entering dormancy. If they sport swollen stems like those in the first photo below, they may only need water once or twice per month over winter. Too much water can cause rot, or mess […]
