I'm looking for information on the annual cycle of irises in the Regelia section and their hybrids with Oncocyclus irises, known sometimes as "Regeliocyclus." When I grew these in frames in large clay pots, kept dry in summer, they did not make significant leaf growth until late winter. Now I have them in a raised bed inside an unheated bulb house, and some of them never really went dormant last summer, even though not watered, and their leaves are almost full size now. I don't like to see this, because I can't grow Onco irises, which make early foliage growth that then succumbs to disease during our humid winters. Did planting the rhizomes out allow them to reach down so deep that they had some moisture throughout summer? (The bed has a commercial woven groundcloth liner over native clay.) Is this bad for them? I saw whitefly on the leaves and placed sticky traps nearby, which seems to have controlled them to a great extent, but I think I'd better use a systemic insecticide on the plants too. I never had aphids in the bulb frames at my former home, but it's considerably colder and windier there, and also the insect population, including predators, is much more numerous and presumably complete as an ecosystem than what one finds in the suburbs. I thought of buying ladybugs (lady beetles), but they are dormant in winter, and anyway they'd probably just fly away through the hardware cloth walls of the bulb house. How do these irises behave for other growers? Thanks, Jane McGary Portland, Oregon, USA
