A Very Reliable Cochlioda Orchid

Monday, November 14th, 2022

This brilliant pink Cochlioda orchid has been a reliable bloomer for years. I bought this charming miniature almost two decades ago, and it flowers every autumn. Each of its spikes can hold over two dozen blossoms which open sequentially, so the pink keeps going for three or four months. This fall, it’s already been in […]

A Little Fuzzy Lady Slipper

Wednesday, August 17th, 2022

This little Lady Slipper is colorful, cute, and fuzzy! Phragmipedium schlimii is native to the slopes of the Andes in Colombia. It’s smaller than most other Phragmipediums, or Phrags, so when I spotted this one for sale at last winter’s Pacific Orchid Expo, I figured I could find room for it indoors. A few months […]

Extraordinary Catasetum Orchids

Tuesday, September 28th, 2021

In Defense of Plants explains why Catasetum orchids really stand out. They have fascinating flowers, but unlike most orchids, these beauties have different male and female blooms. This puzzled botanists long ago, who thought that they were separate species. It was the famous scientist Charles Darwin who finally resolved the confusion. Darwin studied how the […]

The Streaked Rock Orchid: A Tough Mini from Down Under

Wednesday, January 6th, 2021

The Streaked Rock Orchid is a wonderful Australian native. Its strange flowers resemble elaborate birds in flight. Its little, pencil-like leaves turn purplish-red in the sun, making it look like a pointy, colorful hedgehog. In the wild, Dendrobium striolatum lives attached to rocky cliffs in the states of New South Wales, Victoria, and Tasmania. Our […]

Thunia Orchids Grow Fast and Tall

Thursday, July 9th, 2020

Thunia flowers may resemble Cattleyas, but they are very different orchids. Thunias grow tall canes that look like cornstalks, and their 5 inch (12.7 cm) blooms hang in clusters from the tops. They may be the fastest growing orchids. New canes can reach up to 4 feet (1.2 m) tall in only a few months. […]

Vanda Orchids in Glass

Monday, January 27th, 2020

Vandas are orchid royalty, but they can be challenging to grow. They need sun, warmth, regular water, high humidity, and lots of space for their long, dangling roots. Since they don’t like being potted, they’re usually grown on mounts or in baskets, with their roots hanging freely. That makes them difficult for home growers, who […]

Big, Beautiful Vanda Orchids

Sunday, August 26th, 2018

Vandas are orchid royalty. These popular tropical beauties have big, round, colorful, long-lasting flowers. Called strap-leaf Vandas, they are best known in the tropics. In places like Hawaii, it’s easy for growers to accommodate these large plants with long roots and high light needs by tying them onto a tree. Outside the tropics, they’re tougher […]

How To Say Coelogyne

Tuesday, April 10th, 2018

Fortunately, Coelogyne orchids are easier to grow than they are to pronounce. This glorious genus of orchids originates in Southeast Asia, in a large area stretching from India and China to Indonesia, New Guinea, the Philippines, and Fiji. Many varieties have tumbling cascades of fragrant blooms. Their brilliantly-colored flower lips often feature weird ridges and […]

Stenoglottis Orchids, Big and Small

Wednesday, July 6th, 2016

These charming flowers belong to two related orchids, Stenoglottis longifolia and Stenoglottis woodii. They’re some of the easiest African orchid species to grow. The first half-dozen photos show Stenoglottis longifolia. Even though its blooms are small, this species can grow into a big plant. The flowers feature brilliant purple spots and a fringed lip. Dozens […]

Orchids Love Fog

Friday, June 17th, 2016

Orchids love fog. That’s one reason why the Northern California coast is a great place to grow orchids outdoors. Frequent fog, especially in areas closest to the ocean, creates a perfect humid climate for cool growers. Orchids want at least 50% humidity. Fog occurs when levels reach 100%, and the air is saturated with enough […]
