IRIS A genus of 250 plus species running the gamut from aquatics to desert bulbs, there is so much diversity that general comments are meaningless. I would urge gardeners to sample a few plants from the various sections of the genus, most only grew a few bearded hybrids or Siberians and there are so many garden worthy plants that are never even attempted. The Czechs too have collected some wonderful new things. Don't be too intimidated by European pronouncements concerning the growability of various species, a friend and local grower, Brian Radford is growing a wide selection of Oncocyclus species with considerable success outdoors, despite what the pundits might say. If Onco's are possible, the rest should be effortless.
