There is probably no other group of plants equal to orchids in stimulating people's passion!  Nature has produced infinite varieties of shape and color in their flowers, but this is just the beginning.  Because genetic incompatibilities are weak among orchid genera, the horticulturalist is able to not only make successful crosses between species in a genus, he or she can also cross between genera.  

With 880 genera and over 22,000 species, the orchid family is second in size only to Asteraceae.
