< The third squill which blooms here with them is S. mischtschenkoana; < this < one is reliable and with its much larger white flowers much more < conspicuous < than the blue ones. I can't say I have ever seen a white form of this bulb, under either of it's names. It is pale blue with a darker stripe for me. It is certainly the most showy, and least invasive of any of the "scillas", and the earliest here of the common garden forms. although it multiplies and seeds well enough. I have been trying to eliminate chionodoxa luciliae for many years from one bed, and was warned by someone at RHS Wisley about planting scilla bifolia, which is "present" in a large area there.
