Oncidium orchids

Botanical name: Oncidium

Common name: Oncidium

For an exotic flowering display, oncidiums are hard to beat, producing multiple stems of long-lasting, dainty flowers. They are divided into two groups (warm growing and cool growing), according to the conditions they need, and both can be tricky but rewarding to grow as houseplants or greenhouse plants.
