Coelia is easy to pronounce; just ignore the “o” and say “Celia” like the woman’s name. In the wild, it grows as an epiphyte or a terrestrial in rainforests up to 5000 feet (1500 m) in elevation. In cultivation, it needs frequent watering, shady conditions, and winter dormancy. This species tolerates a wide range of temps. However, it doesn’t like repotting, and extra care is needed to avoid damage to roots.

The blooms can be as large as 2 inches (5 cm,) but this plant enjoying life on my back deck has slightly smaller 1.5 inch (3.8 cm) flowers. Besides this variety, another member of the Coelia genus in the final photo has tiny white flowers. This species, Coelia triptera, was on display at a local orchid show. Like Coelia bella, it’s also fragrant.

Australian Dendrobiums, like the next 3 photos, are also popular. Many have rich fragrances. With their incredible diversity, Dendrobiums exemplify the deficiency of one-size-fits-all orchid care instructions. Some grow in hot, steamy jungles, while others grow on cold, windy mountains. As natives to a huge area, from India east to Japan, Australia, and the South Pacific, no single recipe can cover their care. However, they do share commonalities. Most want bright light with morning sun, good humidity, and winter dormancy.

Dendrobium plants come in many forms, but they most commonly have tall, thick plant stems called pseudobulbs or canes. In the next photo, lovely white and purple flowers bloom atop the canes of a Nobile type Dendrobium. Nobile types may drop all their leaves over winter, causing inexperienced growers to think a plant is dead and discard it. Ironically, some kinds flower after they drop their leaves, and their brilliant colors stand out on the bare canes. Other varieties have twisted petals or masses of brilliantly hued blooms.

There’s certainly no shortage of astonishing shapes and colors in the Dendrobium family. They’re true tropical beauties.

One trick to help Cymbidiums bloom is to give them nightly temperature drops of 15-20°F (8-11°C,) especially in autumn. Without this day/night temperature difference, they won’t form flower spikes. Here on the coast, they can grow in full sun. However, growers in warmer areas should provide morning sun and afternoon shade. Plants need enough light so that leaves are light green, not dark green. Cymbidiums enjoy regular fertilizer, and they love compost. They can survive a light frost, although temps below freezing usually damage flowers.

For orchid growers in warmer climates, miniature Cymbidiums like warmer temps. These small varieties are best for growers where summertime temps stay above 70°F (21°C) at night.

This species is native to a vast area of the Amazon Rainforest, across Brazil, Suriname, Venezuela, Colombia, Ecuador, and Peru. The flowers may look delicate, but they’re thick and waxy, and can hold up for months. This type typically blooms in fall and winter.

Thin leaves without pseudobulbs mean this orchid has little capability to store water. It needs daily watering and high humidity. Mine grows in shady conditions, and receives only a little morning sun. The name is easier to figure out than the captivating flower shape; to pronounce Cochleanthes, say “coke-lee-ANN-these.”

With bee populations declining globally, this new info highlights risks for orchid extinctions. Researcher Santiago Ramirez notes “Many of these orchids don’t produce any other type of reward, such as nectar, that would attract other species of bee pollinators. If you lose one species of bee, you could lose three to four species of orchids.”

Inside at Orchids in the Park, the colors began with a blue Dendrobium hybrid, lighter in color than its parent species. Bright colors continued with a pair of Cattleya hybrids which seemed to be inverses of one another. Both had wonderful scents.

A tiny Stelis featured mini flowers, each smaller than the letter “o” on my keyboard, and an elegant Phrag sported petals that drooped down longer than my arms. Rich red Vanda blooms fell into the large flower category, too. A big white Paph captured my attention, but so did the brilliant purple of a mini Phal. Finally, a multicolored hybrid Howeara displayed an abundance of small charms.

Whether you’re in the northern half of the planet entering autumn, or the southern half starting spring, orchids offer lots of reasons to celebrate the change of season.

To pronounce it, say “see-LODGE-in-ee.” This species originates in the mountains of Vietnam, where it grows in cloud forests up to 6500 ft. (2000 m) high. It can handle a wide range of temperatures. Mine lives outside all year in the San Francisco fog, and receives some direct sun.

Coelogynes like frequent waterings during spring and summer, and less during winter dormancy. They enjoy regular fertilizer, high humidity, and good air movement. Almost 200 different Coelogyne species include varieties to suit warm, intermediate, or cool climates. They’re great for beginners who are ready to try a challenge beyond hybrids.
