Oncidium spp.

flower

Small Oncidium orchids are miniature to intermediate-sized epiphytic orchids prized for their abundant, delicate flowers in shades of yellow, pink, white, and red. Known as 'dancing lady' orchids, they produce sprays of small, intricately patterned blooms that can flower prolifically indoors. These orchids are popular houseplants due to their relatively forgiving nature compared to other orchid genera.

Growth Stages

1

Dormancy

2-3 months (typically fall/winter)

Plant rests with minimal growth; pseudobulbs appear slightly wrinkled

Reduce watering and feeding; maintain cooler temperatures (55-65°F at night); allow for drier periods between waterings

2

New Growth

2-3 months

New shoots and pseudobulbs emerge; fresh green foliage develops

Resume regular watering and feeding schedule; provide bright light; maintain warm daytime temperatures (70-80°F)

3

Vegetative

1-2 months

Plant develops full-sized pseudobulbs and mature leaves; foliage is thick and healthy

Maintain consistent moisture (not soggy); feed every 1-2 weeks with diluted orchid fertilizer; ensure high humidity (50-70%)

4

Blooming

4-12 weeks depending on variety

Inflorescences emerge from base of pseudobulbs; delicate flowers open in succession over weeks

Maintain bright light and moderate humidity; reduce nitrogen fertilizer in favor of phosphorus-rich bloom formula; avoid moving plant

5

Post-Bloom

2-4 weeks

Flowers fade and drop; plant prepares for dormancy or initiates new growth

Allow spent inflorescences to remain if new shoots haven't emerged; gradually reduce watering if entering dormancy; prune dead spike above basal node if desired

Fun Facts

  • 🌱 Oncidiums are called 'dancing lady' orchids because their petals resemble the skirt of a woman dancing—the large lip (labellum) appears to be a lady in motion.
  • 🌱 Small Oncidiums can flower multiple times per year with proper care, producing hundreds of blooms from a single plant, making them excellent value as houseplants.
  • 🌱 Oncidiums are epiphytic orchids that naturally grow on trees in tropical rainforests, which is why they require excellent air circulation and free-draining bark medium rather than traditional soil.
