Most are very long-lived. In fact, some species are virtually immortal, given the proper attention. Again, it depends on the plant. The most popular types bloom in winter and spring, but orchids may be found that bloom in any month of the year. That's one of their greatest assets.
Orchids are portable.
Because they grow in pots or baskets, they can be carried anywhere. Many growers use blooming plants as living centerpieces in their homes. Orchids are routinely mailed and shipped across country and around the world. There are many excellent books available to help a novice grower learn more. Most bookstores and public libraries have them.
