What species (and/or cultivars, hybrids) are you growing?
I have a number of stricta varieties and hybrids (they're easy to grow and bloom), cyanea (can't beat the display on that and lovely fragrant blooms) as well as things like fuchsii, variabilis, ixioides, diaguitensis, usneoides, and a several others I've forgotten the names of or which are NOIDs.
