Moth Orchids, or Phals, have been popular Mother’s Day gifts for years, but sometimes it’s time for something different. The orchid world has endless variety to choose from; these photos show just a tiny sample of what’s available besides Phals.

Researchers Identify Oldest Orchid Fossil

Scientists have identified evidence of the oldest orchid fossil on record. Preserved in amber between 45 and 55 million years ago, a tiny gnat is carrying a tinier bundle of orchid pollen. “We probably shouldn’t say this about a plant, but orchids are very smart” laughed George Poinar, Jr., entomologist at Oregon State University, and lead author on the newly published discovery. It’s likely that orchids first evolved in the Cretaceous Period, blooming alongside the dinosaurs, and they’ve been enticing pollinators for tens of millions of years.

The San Francisco Botanical Garden is bursting with new growth after a rainy winter. Covering about 55 acres (22 hectares) of Golden Gate Park, the garden is always full of life. During a recent visit, there were lots of spring blooms, and everything from tree ferns to giant redwoods were sporting new greenery.

When You’ve Killed Your Weight in Orchids

There’s a saying that you become an orchid expert when you’ve killed your weight in orchids. Some people wince in horror when I repeat that, but orchid lovers usually just laugh and nod. Growing orchids means sometimes making mistakes and killing plants. I’ve grown them for over 25 years, and earned my expert status a very long time ago. Fortunately, my mortality rate is far lower than it once was.

These photos are all orchids I’ve killed. Many are older plants which are long gone. In fact, a few of these photos are a dozen years old. Some died because I watered too much or not enough, forgot to repot, or let pests get out of control. Others died for reasons beyond my control, like raccoon damage, or having a short lifespan. Most importantly, I’ve tried to learn from each of them, even if it was only about the limits of the growing conditions I could provide.

Now, don’t get the idea that I used to run some type of orchid slaughterhouse. I have orchids which have thrived for decades, despite this visual record to the contrary. Whether beginner or expert, all growers need to continue learning. With tens of thousands of species and countless hybrids, orchids are an endless field of knowledge. There are always more mistakes to make, and more orchids to kill.

Rare Orchid Discovery Halts Aussie Racers

Rare orchid populations have stopped plans for an Australian race park. Orchid lovers found Leafless Tongue Orchids near the planned track. That’s pitted nature lovers against racing fans, but local officials have stated that the building plans had many flaws, including the fact that the area is home to lots of endangered species. The Leafless Tongue Orchid, Cryptostylis hunteriana, is one of many strange Australian plants. It’s a terrestrial found only near the country’s southeastern coast. With no leaves to photosynthesize, it’s believed to draw nutrients from fungi and decaying leaves. The orchid has been classified as vulnerable and is protected by Australian law.

Ground Orchids Bloom in Tough Spots

Spathoglottis, or Ground Orchids, are staples of the tropics. They’re sturdy enough to serve as landscaping plants in shopping plazas, like these orchids on the island of Kauai.  Grown alone in pots, or in flowerbeds with other tropicals, they make gorgeous displays.

These terrestrials are easy to keep in the tropics, but hard to grow elsewhere. They need lots of direct sun, warmth, water, and fertilizer to bloom. For tropical gardeners, and others with warm greenhouses, there are several species and an ever-expanding number of hybrids to choose from. Many can become large plants, but there are smaller varieties available, too.

The next photo below shows the only one in this post that’s not part of commercial landscaping. The bloom belongs to a wild plant next to a desert stream in Waimea Canyon. The Philippine Ground Orchid, Spathoglottis plicata, has naturalized in Hawaii. Surviving in a hot, dry environment, it’s demonstrating the same toughness that allows its relatives to thrive in a concrete planter near a parking lot. For gardeners in the tropics, Ground Orchids can provide great blooms for tough spots.
