I’m curious to find out what these are because to my knowledge I never planted anything except a few geraniums. Perhaps I reused soil from another container that had supported tulips, but these green shoots don’t look like tulips to me.
Yoga day 17/18 complete, three Duolingo units, two squares of cross stitch, and a phone call with #2 son - two feet (he says) of snow in Aberdeen. I think this might be an exaggerated estimate.
