AboutOrchids

Orchids have become essential for Valentine’s Day. If your celebration of love includes a gift orchid, check the care tips below.

What kind is it? –  Identify your orchid to learn more about its care needs. Phals, or Moth Orchids, are the most common types. Other popular varieties include Cattleyas, Cymbidiums, Dendrobiums, Oncidiums, and Paphs.

Light – Place your orchid in bright light. Many kinds enjoy some direct sun, especially while light levels are low in winter.

Humidity – Orchids hate dry air, which can wilt flowers, damage leaves, and attract pests. Raise humidity by grouping plants together, or placing plants in a humid area, like a bathroom or kitchen. To increase humidity, use a cool mist humidifier, or a spray mister. Balance flowerpots on pebbles in trays of water, always keeping the pots raised above the water level.

Water – Use room-temperature water to soak the pot, and then let all excess water drain out. Don’t let plants sit in water for too long, or their roots may rot. If wrappers, ribbons, or decorative containers block the holes in the bottom of the flower pot, remove them to allow drainage and air flow.

Cut flowers – Give orchids the same care as other cut flowers. Place them in lukewarm water, and keep out of direct sun. Change the water every couple days. High humidity will help the flowers last longer.

Are they Phals or Dendrobiums?  Den Phals are Dendrobiums, and they’re very popular orchids. Also called Phalaenopsis-type Dendrobiums, or Phalanthe-type Dendrobiums, their confusing names derive from their resemblance to Phal flowers. They represent a small section of the large Dendrobium family, but they’ve become some of the most commonly cultivated varieties.

Den Phals come in a range of whites, pinks, and purples, and there are even some with green blooms. They’re popular as potted plants. As cut flowers, they’re often used in bouquets, as food garnishes, and to make Hawaiian leis. Their flowers do look similar to Phals, or Moth Orchids, and it can be tough to distinguish them.

Fortunately, there’s an easy trick to tell Phals from Den Phals. While their flowers may be similar, they have very different plants and leaves. Den Phals grow tall canes, or pseudobulbs, that look like thick stems, and their leaves are narrow and pointed (see the first photo below.)  On the other hand, Phals have broad leaves which are connected at their base, without any central stem (see the middle photo below for Phal leaves, and the final photo for a Phal bloom.)

It’s important to distinguish them because their care needs are different. Den Phals need more sun that Phals, and can handle a wider range of temps. Let Den Phals dry between thorough waterings. They don’t need a dormant period, but growers outside the tropics should cut back water and fertilizer in the lower light and cooler temps of winter. Den Phal flowers can last for weeks, which helps contribute to their popularity.

Many botanical gardens offer extended orchid exhibits over winter. Be sure to take advantage of these great escapes from the cold.

Cynorkis fastigiata is an unusual orchid from some unusual islands. It would be easy to mistake for a couple blades of grass, except for its strange flowers hovering above. This small species is native to Madagascar and nearby islands in the Indian Ocean: the Seychelles, the Comoros, Mauritius, and Reunion.

This species can grow as a terrestrial or an air plant. It needs regular water, high humidity, and warm temps during spring and summer. Cynorkis drops its leaves and goes dormant over winter, but shouldn’t be allowed to dry out. As a confession, I’ll admit that I think I’ve messed up the dormancy period with my plant. It has bloomed twice this year — once in April, and again with fresh leaves and flowers over the past few weeks. It may not survive the winter, but at least we have another set of photos from this bloom. Please keep your fingers crossed for me, and I’ll keep you updated on its progress.

My plant seems to self-pollinate, and every flower forms a seedpod. I suppose that explains its reputation for being invasive in greenhouses. It’s known as one of the few orchid weeds (check out the Bamboo Orchid and the Philippine Ground Orchid for other examples.) So far, mine hasn’t spread to any other nearby pots. If it survives, maybe it will have more chances to earn its weedy reputation.

Have you found an orchid growing in the wild, but can’t identify it? Go Orchids is an excellent online tool to learn about varieties native to the USA and Canada. Courtesy of the North American Orchid Conservation Center (NAOCC,) Go Orchids lets you search by location, by name, or by a series of botanical questions. Their online roster of native orchids is not yet complete, but it’s already a great resource, and more listings are being added soon. There are lots of photos to help with your online search, and also an extensive glossary to assist with the site’s botanical vocabulary.

The NAOCC works to conserve North American orchids by preserving habitats, propagating endangered species, and educating the public about these native plant treasures. This non-profit organization partners with botanical gardens and conservation groups to best combine their resources and knowledge.

Go Orchids can help you identify that wild mystery orchid. Please remember that it is illegal to take native orchids from the wild, and with their specialized growing needs, the plants are unlikely to survive anyway. Do not pick wild orchid flowers, either, or you rob them of any chance to contribute to future generations. If you find orchids in the wild, take only memories and photos, and leave nothing but footprints. And check Go Orchids!
