These techniques allow many hundreds of orchid plants to survive to maturity. New and improved hybrids can be mass produced rapidly. This is important as orchids are very slow growing. Many orchids take five to seven years to mature to flowering. You can see why breeding three or four orchid generations could span a person's lifetime just to get one new hybrid propagated sufficiently for sale.
Monopodial orchids have a central stem which grows continuously from the tip.
Flowers are produced from the stem between the leaves, usually alternately from side to side. Phalaenopsis orchids are a good example. Sympodial orchids, such as cattleyas, laelias and paphiopedilums, possess a rhizome which sends out a shoot. This develops into a stem and leaves and eventually produces flowers. In time, from the base of this growth, a new shoot develops and so on in a continuous cycle.
