Creeping Jenny blooms. This is why I love my weeds.

June 12 update: Deptford Pink (Dianthus armeria)

I feel pretty sure that this is it. And deer don't like it according to one website that says;
"The foliage of members of the Pink family tends to be high in saponins and unattractive to mammalian herbivores."

Cranesbill (Geranium endressii)

3/1/11 update: Thanks to Patricia Newport for the ID.

10/10/10: White boneset or thoroughwort. I'm letting it bloom but I won't let it grow next yr. Takes up too much real estate in my veggie garden.

Forget-me-not (Myosotis sylvatica).

I think Michelle and Theora are right: this is a forget-me-not. And I also think I have a vague memory of planting some seeds for this last year. They look so weedy coming up that I'm sure I've yanked up a bunch of them before they could bloom. If they survive the deer, they'll be keepers.

Sowthistle (Sonchus arvensis). [5/24/10 update]

Here's a picture from last year. I'm letting them spread. They're weedy but are also pretty, in a modest, plain-jane way. And I STILL don't know what they are.
