Ah yes, among my first bulbs I planted as a teenager were Chionodoxa and Siberian Squills, and within a few years both, which were planted at the front of the bed, started seeding in the lawn. I recall them blooming before those planted in the garden too, I suppose the sod provides warmth that mulch doesn't. I like seeing little flowers move into the lawn, but the other way around irks me, LOL.
