Susan, any change with your Snowdrops this year? I have one little clump of them in bloom right now, such sweet little things. I also realized that the spot where they're growing is one where I filled in with a bunch of soil and compost, so now those bulbs are quite deep. Didn't stop them though. I noticed I'd suggested above that perhaps yours were too deep, which sounds doubtful with your hard soil anyway, but now I see that wouldn't stop them.
