Blooming How often orchids bloom depend on the variety plus factors of culture and care. Blooms of hybrids of the Cattleya family may last up to four weeks on the plant. Those of the Phalaenopsis family commonly last from one to four months. Large plants of Phalenopsis will re-bloom on a secondary spike, if the active spike is broken just below the first flower. The most popular orchid types bloom in winter and spring, but orchids may be found that bloom in any month of the year.
Most orchids are very long-lived.
In fact, some species are virtually immortal, given the proper attention.
