Orchids are important symbols for many nations. The countries listed below have picked native orchids as national flowers, and proud emblems of their natural heritage. Many hold special meanings, often associated with important holidays. Some of these species are endangered, and their national status helps promote their conservation.

Rare Orchid Discovered in Buckingham Palace’s Gardens

Exciting news from Buckingham Palace! Yes, there’s a new baby prince, and there’s also a rare orchid growing on palace grounds. Orchid lovers are excited about the news of the orchid species, which hasn’t been seen anywhere in London for over a century. The unexpected find is a White Helleborine Orchid, or Cephalanthera damasonium, a terrestrial native to Europe and Asia. Botanist Dr. Mark Spencer remarked “It is quite unusual to find the white helleborine north of the Thames, let alone in the middle of the city in the Queen’s back garden. It shows just how important green spaces are in built-up areas for giving wildlife a refuge.” The orchid was found by the London Natural History Society and the Botanical Society of the British Isles, which are jointly cataloging London’s greenery. So far, they’ve found over 450 types of plants in the palace garden. It makes a great botanical welcome for the new royal heir.

Mini African Orchid Species

South Africa has so many fascinating native orchids that they seem to overshadow this mini species. Maybe that’s why this charming Mystacidium isn’t common in cultivation. However, it is one of the most common orchids found in South Africa. Last summer, I blogged about my plant’s impressive display, and this year, it’s unfurled an even bigger show. Its masses of elegant, pure white flowers hang from the small plant, and emit a strong jasmine scent after sunset.

Don’t be fooled by this plant’s delicate appearance. Mystacidiums are tougher than they look. They can handle high heat and dry air better than most orchids. In their native habitats, they live in arid climates where few other orchids can survive. In dry woodlands and savannas, they grow attached to trees and succulents. These Vanda relatives have also adapted to South African citrus farms, where they grow as weeds on the trees. With this tenacity, Mystacidiums are great choices for growers in warm climates, and also for orchid lovers who want to grow mounted plants.

An Orchid Disguised as a Weed

The New York Times uncovers an orchid weed. Epipactis helleborine, known simply as helleborine, is an old world orchid species which has taken over North America, too. The fact that it’s happy in a wide range of growing conditions and soils, and can even grow in asphalt, helps explain its spread from coast to coast. Even in New York City, helleborine reliably sprouts in sidewalk cracks, driveways, rock walls, and gardens every year. “As a weed, helleborine proudly holds its head up with dandelions, dayflowers, horseweed, mugwort, plantains and smartweeds, but helleborine is an orchid, whose modified lip and floral structures are as tropical looking as any orchid growing in the Brooklyn Botanic Garden or the New York Botanical Garden in the Bronx.” Helleborine is closely related to the Stream Orchid, the native North American species that I grow.

Fungus a Lifesaver for Rare Orchids

Conservationists in Australia are relying on fungus to save endangered orchids. Like most orchids, the Rosella Spider Orchid and The Wine-Lipped Spider Orchid grow with the help of fungus. Both orchid species have declined due to habitat destruction, grazing, invasive species, and development. To help reinforce the remaining wild populations, researchers and volunteers plan to start seedlings at the Royal Botanic Gardens Melbourne, and then transplant them into the wild.

However, growing orchids from seed is complicated. Orchids and fungi form symbiotic relationships to exchange nutrients, and orchid seeds need a fungus to germinate and grow. Since different types of orchids need different types of fungi, conservationists need to identify and cultivate the correct fungus for each variety. After seeds germinate, it will take two years before the young plants can be transplanted into the wild, and four or five years before they are mature enough to flower. It’s intricate work that requires lots of patience. Biologist Tom May commented ”What is happening in nature is so complex. The interactions between the fungi and the orchids being pollinated by wasps is just the start. You’ve got to put all the pieces back together again.”

Summer Blooms

It’s been awhile since I’ve shared pictures from our back garden, so I went out with my camera during this week’s warm spell to snap a few shots. From Violas to Lily of the Nile to Nasturtiums, there’s plenty in bloom.

There are always orchids in bloom on the back deck. One of my favorites, a Masdevallia species from Bolivia, flowers reliably every summer. My old pink Cymbidium blooms over winter, and usually drops its flowers in spring. However, this year it’s been happy enough to keep blooming into summer. The last picture shows a fuchsia. From similar humid jungles as orchids, they all love San Francisco’s fog.

Another fuchsia with smaller blooms shows why they’re local garden favorites. Finally, small succulents have interesting architectures, demonstrating that flowers aren’t always necessary to stand out in a summer garden.

Easy Breezy Orchids

Posted June 25th, 2013 by Marc Cohen
Categories: Growing

Like people, orchids need to breathe fresh air. A stale or stagnant environment leads to pests and diseases. Moving air evaporates excess water, and cools leaves and roots.

In their wild homes, orchids live in gentle breezes and strong winds. As air plants, their leaves and roots blow in the rainforest canopy. In homes and offices, orchids need good ventilation.

To improve circulation, keep plants near an open window, or turn a fan on slow speed. When it’s warm enough, move plants outdoors.

Growers in homes and offices often rely on heaters and air conditioners for air movement. Be sure to keep humidity high; orchids want moist breezes. Providing fresh air is an easy way to help your orchid breathe.
