Which Orchids Have Pseudobulbs?

Types of epiphytic orchids that have pseudobulbs include the genera Cattleya, Dendrobium and Oncidium. Cattleyas grow in U.S. Department of Agriculture plant hardiness zones 10 through 12, and Dendrobium and Oncidium orchids grow in USDA zones 9 through 12.

Do all orchids have pseudobulbs?

What is a pseudobulb? Unlike most houseplants, orchids don't grow from seeds or rooted stems. Most common orchids grown in homes come from pseudobulbs, which are pod-like structures that grow directly below the leaves.

How do I know which type of orchid I have?

If you do not have the original tag identifying the orchid, then the easiest way to identify it is with the flowers. Look at the shape, color, patterns, and size of the bloom. Most orchids come in many colors, so you cannot identify an orchid solely by the color or size of the flower, but it may help narrow it down.
