When is a rose not a rose? Maybe when it’s an orchid that smells like a rose. This mini orchid has small flowers with big fragrance. I’ve blogged before about this beautiful Caucaea species. It’s an easy cool grower with a delicious rose scent.

Last autumn, this plant’s blooms were damaged during a windy storm. Happily, it grew a replacement spike last month. Despite its diminutive size, I can catch its perfume from several steps away in our back garden. It’s proof that a rose by another name can smell just as sweet.

Orchids with the Easiest Names

Posted January 22nd, 2025 by Marc Cohen
Categories: Misc, Orchid Names, Photos

Moth Orchids, Lady Slippers, and Pansy Orchids have easy common names, but most orchids don’t. They have their Latin names, which can be daunting. Understandably, many people are intimidated by long, scientific words. Fortunately, not all of them are difficult. Check out this list of 10 orchids with Latin names that you don’t have to stumble over.

Ada – This genus has been renamed as Brassia, which is also included in this post. Some are cool growers, like the brilliant orange Ada pictured below.
Bletilla – Bletillas, or Chinese Ground Orchids, are good garden plants. They can be grown as tender bulbs in rich soil.
Brassia – With long petals, Spider Orchids come in a variety of species and hybrids.

Eria – These Dendrobium relatives aren’t common in cultivation. They can be very striking, like the white blooms below.
Ida – This is another uncommon genus. Idas can be large plants with big flowers, including dazzling green ones.
Laelia – Members of the Cattleya family, many feature elegant blossoms with bold colors, like Laelia anceps, Laelia gouldiana, and the purple hybrid pictured below.

Mexicoa – These charming Oncidium relatives have a lemony fragrance. As their name suggests, they’re native to Mexico.
Thunia – Fascinating Himalayan orchids, Thunias look like corn stalks with big, showy flowers dangling from the top.
Vanda – Emblematic of the tropics, Vandas come in a wide variety of colors and sizes.
Vanilla – Vanilla vines are fairly easy to grow, but challenging to bloom outside the tropics. Many forms sport variegated leaves.

A Season of Orchids

Celebrate today’s solstice with orchids from our garden. All these photos are from this autumn. The season changes with some blooms already fallen, but others still going strong. As the days start to lengthen after the winter solstice, new cycles of growth will begin.

This Vanda Orchid Is a Flower Machine

This Vanda is a flower machine. It keeps blooming, and it’s grown well enough to need a bigger vase. I blogged before about the handy Vanda trick I use. These orchids are normally kept mounted, in baskets, or bare root. Those methods can be challenging for home growers outside the tropics. They’re much easier to care for in a vase. This hybrid reliably blooms twice a year, boasting showy, purple blossoms for three months at a time.

Each flower is big and round, but not flat, with a dark lip sticking out of all that purple. When I moved the plant to the larger vase, I worked as many of its thick roots as I could inside the glass. They hold the plant in place, and counterbalance the big flower spikes.

Watering is done by regularly filling the vase, and letting the plant soak for a few minutes. Then pour out most of the water, leaving a shallow layer at the bottom to keep humidity high around the roots and leaves. It’s easy to fertilize weakly, weekly. I try to keep the roots clean of moss and algae. With warm days and morning sun, it’s relatively easy to enjoy lush, tropical orchids. With these growing tips, you may be able to have your own flower machine.

Wild Orchid Collectors: A Key Driver of Decline

Posted November 24th, 2024 by Marc Cohen
Categories: Conservation, In the News

Orchid poachers are one of the biggest threats to orchid survival. Private collectors who take plants from the wild, or who buy wild plants, can wipe out native populations. Social media has worsened the problem, directly connecting poachers and buyers. Viral fads can cause rare varieties to be completely wiped out, and can even jeopardize common species. Conservation laws are often inadequate and difficult to enforce. It’s a huge issue in all orchid hotspots, including Southeast Asia.

Conservation groups like the Orchid Specialist Group at the IUCN are trying to tackle the problem. They’re publishing guidelines on sustainable practices, and doing outreach, too. While not condoning illegal collecting, they are trying to work with collectors to reduce risks of destroying wild populations. In Vietnam, Indonesia, and the Philippines, they’ve been interviewing and educating people, trying to change behaviors with accurate info about laws and imperiled varieties. Learning how to sustainably propagate endangered species may lessen threats to native plants, while also providing income for local communities. Conservationists are hoping that poachers who are harming the environment might be part of saving it.

We can all help by never taking orchids from the wild, or buying plants which have been poached. Only purchase from responsible vendors, and be especially cautious of online vendors. Ask if you’re not sure. Instead of species, buy human-made hybrids. Check out these additional tips to know if a plant is illegally trafficked.

A Dancing Lady Orchid on the Rocks

A couple years ago, while repotting a Dancing Lady Orchid, part of the plant broke off. With a few leaves, roots, and pseudobulbs, I could have put it the small piece back the pot with the rest of the plant, but I decided to experiment. We have a few large stones in the backyard, shaded underneath a juniper tree. There was a shallow divot in a rock where the cutting fit well. With a little bit of glue and moss, I set it in place. Since then, it’s attached itself to the rock with new roots, and it’s been blooming for a couple months. Originally, I thought that it might be too shaded by the tree, and wouldn’t receive enough light to bloom, but it’s proven me wrong.

Dancing Lady Orchids, or Oncidiums, are popular houseplants, and some types are cool growers which enjoy our foggy climate. This one appears happy growing as a lithophyte, or “rock plant.” It started as an office orchid that Dave brought home years ago, without a nametag, thus earning its status as “Oncidium NOID.” There are lots of Oncidium hybrids, and it might be an impossible task to pin down a name.

While the mother plant continues to grow well outdoors in a pot, its flowers were devoured by snails this year. Maybe the rough stone keeps the snails away from the rock plant. Its flowers have already weathered strong winds and chilly nights, and they’re still going. It’s an orchid experiment that’s definitely been paying off.
