Larkspur is the easiest flower I know of. I save the seed and scatter in the very early spring and that's it. It will soon be going in this hot weather but this clump is getting afternoon shade.
Silvery Fir tomato from seed by Botanical Interests. This is three plants, the foliage is very nice and we will see how the tomatoes are. There are lots of green ones. It looks nice enough to be among the flowers.
