The photo is of scilla (Siberian squill)... a little bulb with a short life but very beautiful. They reseed and spread quickly.

When we moved in here there was a patch by the back door about 6ft by 4 ft. It is now moving thru our whole yard. (almost a 1/4 of an acre --the yard is 1/2 acre--- and when it blooms all at once it is a total blue carpet. Then the leaves die back and for about 10 days are slimey and icky...but I think it is worth it.
So hubby rakes in the direction away from the house, and the seeds disperse outward.

The ants also carry the seeds around. I used to sit out on the front steps down in front (we live on a hill), with my son and wait for Daddy to come home from work. I'd watch the black ants carrying the seeds around! Some get stored, and some planted that way. We have the scilla in the rock gardens down in front from that method of dispersal too!

I put my garden things in my siggie (and sometimes avatar) all during the growing season....you see them soon!
