Summarize this article in one sentence.
Younger plants or seedlings may seem like a good value, but some orchids can take years of advanced care before blooming. To avoid this, select a plant that has visible blooms or at least flower spikes. Limp or wrinkly leaves can be a sign of poor care. The leaves should be thick, lustrous, and even rubbery. They should also be a uniform green unless it is a mottled species.

Summary:
Purchase a mature plant. Look for vibrant leaves.
