Inside the blooms are the stylis with the stigma, fused with the filament and anther. When the pollen comes in contact with the stigma, the bloom will rapidly wither and the ovary located at the base will expand into a pod, which will take from six months to one year to ripen. As maturity peaks, the full grown pod will burst open longitudinally and the mass of minuscule seeds inside will be distributed into the air. Some of these pods can contain millions of seeds. The seeds will be, air-borne until, with great luck, some land on a spot of a host tree which happens to be covered with a kind of fungi called mycorrhiza which is essential to help in finding food during the first part of the seedling's growth, until it can mature into another orchid plant.
Most wild orchids bloom only once a year.
Those that do so more than once are rare. Whereas the Rhyncostylis retusa follows in April and May right along with Aerides odorata , Aerides falcata and Aerides multiflora . July and August is the time for Vanda coerulea . Those mentioned are only some of the more prominent and better known ones. There are quite a lot more orchids which bloom at different periods of the year.
