First Signs of Spring

Tomato and pepper plants went in this past weekend!

Flowers will fill out the planter over the next few weeks, no doubt.

Cowbells and purple whatever-they-ares are blooming!

Can anyone identify the white plants to the right of the cowbells? They're wildflowers and come in white and light purple varieties. I'd like to get some more to plant in a dry spot in front of my house, since they seem to be drought-tolerant.

FYI, my pond's stream runs down the channel just to the left of the cowbells. It wasn't running when I snapped this picture, though.
