Orchid Types: Oncidium vs. Phalaenopsis – The Two Major Groups

Thousands of orchid types exist. Start by dividing into two families:

Oncidium (Largest Group)

Petite blooms with oversized "lip" at 6 o'clock. Familiar in hotel displays, weddings. Branches = sprays (100+ flowers each). Multiple plants = impossible-to-match arrangements. Most diverse.

Phalaenopsis (Phals)

No large lip; larger flowers. Less diverse naturally, but thousands of human-made hybrids. Called "Phals" (not "Paphs"—Paphiopedilum, a sub-group).

Ideal for small arrangements, centerpieces. Easiest commercial crop. Global corsage/premade market huge. Flowers to 6 inches, white-to-purple spectrum. Florist favorites.

Growing in America

Neither native (except some Florida Oncidiums). Moist/warm environment easily simulated. Proper care → annual autumn blooms. Post-establishment, they're low-maintenance.
