I'm working on an article on bulbs small enough to be suitable for cultivation in troughs (the concrete-like basins often used for the cultivation of alpines and small xeric plants). The main criteria are : (1) short stems; (2) slow to moderate rate of increase; (3) attractive flowers; and (4), most important, low-lying or sparse foliage that will not look messy as the bulbs mature. There are many well-known bulbous genera that have little-known miniature members (e.g., Colchicum, Narcissus). Can forum members suggest some of their favorites that would be suitable? I particularly need information on genera I don't grow myself, such as Australian and South African ones. Thanks in advance, Jane McGary Editor, NARGS Rock Garden Quarterly
