After looking at some photos, I have realized that one of the weeds in my garden is a bittercress species. In my climate, it is a relatively inoffensive plant that spreads in winter and vanishes in late spring, so it really doesn't bother spring and summer growing bulbs. The real thug in my garden is Japanese stiltgrass (Microstegium). Bulbs don't stand a chance. It will sprawl over fairly large bushes and smothers any flowerbed that doesn't get a good thick layer of mulch regularly. Copperheads like to hide in it, which makes weeding exciting.

I have lost count of how many times it bloomed this year.
