Spring Orchid Checklist

Saturday, May 28th, 2011

By the end of May, San Francisco’s rainy season has usually given way to the dry season, but this year’s weather seems anything but typical. Fortunately we’ve had nothing like the violent storms in other parts of the country. Instead, a cool, wet spring is keeping the garden well hydrated. The light rains and mild [...]

Ada

Tuesday, January 4th, 2011

No long orchid name to battle here! Adas announce themselves with brilliant color. This mass of orange petals contains multiple flowers, and looks somewhat like a mound of shredded carrots. Fortunately, a solitary blossom also stands out for the camera.

Related to Odontoglossums and Oncidiums, this Ada species is native to the Andes. It lives as [...]

Wacky Weather

Saturday, November 20th, 2010

Last week, before Dave and I went to Philly to visit family, I’m glad I gave my neighbor George last minute instructions to “water everything!” We’ve had November warm spells before, but when I heard Bay Area forecasters using the words “offshore flow,” I knew it was going to be a mini heatwave. Most of [...]

Samurai Orchid

Sunday, October 10th, 2010

Centuries before the western world became fascinated with orchids, some eastern cultures were cultivating and revering them. For over 400 years, Japanese have grown fuu ran, the “wind orchid.” It’s known in English as Neofinetia, or the Samurai Orchid. This mini species is native to mountainside forests in southern Japan, southern Korea, and eastern China. [...]

Equinox

Wednesday, September 22nd, 2010

To celebrate the arrival of fall, here are some garden beauties:

Autumn arrives in the Northern Hemisphere with a chill, shorter days, and some orchid chores. As temperatures drop, bring warm growers inside. Remove any dead leaves or weeds. Check for pests, especially those hiding on the undersides of leaves. I spray orchid plants and potting [...]

Thunia

Friday, June 25th, 2010

If you saw a Thunia without flowers, you be forgiven for thinking it was a cornstalk. When it’s in bloom, however, there’s no doubt that it’s an orchid. Thunia flowers look like Cattleyas that haven’t opened completely. The 5 inch (13 cm) wide blooms hang in clusters, pulling down the tops of their 4 ft. [...]

Stream Orchid

Saturday, June 5th, 2010

My own orchid collection has species and hybrids from all over the world, but only one that’s native to San Francisco. It may be less glamorous than its tropical relatives, but this Epipactis, or Stream Orchid, really enjoys the local climate. This species has a large range over western North America, spanning from Canada south [...]

Spring Forward

Saturday, March 13th, 2010

Northern gardeners who are enduring a long and snowy winter may take some solace that spring is arriving in San Francisco. The old Japanese Maple in the back garden is leafing out, and the leaves of my Sobralia have turned light green, telling me that the sun is strengthening. We had to endure [...]

Hyacinth Orchid

Thursday, January 7th, 2010

January’s chilly start has been perfect for this beautiful Arpophyllum. Here on the California coast, this Cattleya relative is blooming outdoors on our back deck, and it’s easy to see how it acquired the nickname “Hyacinth Orchid.” This gorgeous plant was a gift from Dave’s parents, and it’s proving to be a reliable bloomer over [...]

Winter Orchid Care

Sunday, December 27th, 2009

There’s no better reminder than the harsh winter weather that many orchids have entered a dormant season. Corresponding to a dry season in the wild, members of these common orchid families are resting like a bear in a cozy den. Resist the urge to water until you see their pseudobulbs start to shrivel. Do your [...]
