I can't answer the implied questions about being in the midwest and in zone 5B, but I can tell you that clay is an excellent soil to grow many bulbs in, including snowdrops. It holds nutrients very well by adsorption (not absorption), which helps bulbs grow well. An exception is lateritic clay, such as is found in the Oregon Coast Range and the Amazon basin. Because of structural differences at the molecular level, lateritic clays do no adsorb nutrients very well at all. It's a common misapprehension to think that "bulbs require summer-dry soil" means "bulbs like sandy soils." While some bulbs do, indeed, like sandy soils, most bulbs are very heavy feeders and prefer a fairly heavy soil. As long as it's dry, sunnym, and fairly warm in the summer, most of the time clay is a far better soil for bulbs than sand. It should be obvious that bulbs are heavy feeders: how else do they manage to build up the fleshy storage organs that characterize them? Another myth is that bulbs should be overplanted with ground covers. This may work for the more vigorous bulbs, but groundcovers shade the soil and may prevent it from warming up enough to initiate flower bud formation. Snowdrops in particular generally like a situation that is fairly damp, even wet, in winter. -- Rodger Whitlock Victoria, British Columbia, Canada Maritime Zone 8, a cool Mediterranean climate on beautiful Vancouver Island http://maps.google.ca/maps/…
