I like to have flowers in the house but I'm terribly mean about picking them from the garden. One rose and a lot of Lady's Mantle, that's my style. The kitchen posy above is just a few geranium flowers with Lady's Mantle and some flax (a weed). Below: Acanthus mollis, phlox, Eryngium giganteum (Miss Willmott's Ghost). I have far too much of Miss Willmott; I should never have let the first plant seed.
You can't be mean with sweet peas, as the whole point of them is to pick, pick, pick every day. They might get a post to themselves.
