I have another bulbous species to mention, rather an easy one to overlook: Geranium tuberosum. Sparse, relatively small pink flowers are borne right now, 12" above quite nice foliage; dormancy ensues in 3 or 4 weeks. It does perfectly well in a sunny, well-drained position. I haven't been strongly motivated to try it elsewhere in the past but more recent efforts have worked out well enough. Along with other respondents I struggle to control Chionodoxa lucillae and Endymion non-scriptus, at the same time quite enjoying the show in proper season. Nonetheless, too much has gotten to be too much and has prompted me to get an ultimate weapon: a shovel (perhaps a post-hole digger? I didn't take in its nominal identification) that is 16" long and 5" wide, compared with the 10" x 7" of my more typical spade. Those extra 6 inches are enough to get down to the bulb zone, loosening the soil sufficiently that the bulbs can be eased out intact. Disruption can be kept fairly minimal.
