I recently bought Lauren's Grape Poppy seeds to plant for the upcoming spring/summer season. What flowers would be good to plant in front of them to hide the fading foliage around mid-summer? I want to stay in a white, pink, and purple color scheme. Thanks for any info.

I plant my grape poppies with Lilies...end of the Asiatics, beginning of the Orientals....there are other plants in the bed too that help to provide camo for the fading poppies (artemesia, garden rue) plus I sometimes still have later delphs - there used to be roses but no more. Here's a not so good picture but you may get the idea

I've white daisies and yellow yarrow, thinking of transplanting with the red poppies. They're too long and gangly with other plants I have them with now. Also thinking of annual poppies, waiting for the right season

Snow daisies are short. (annuals)
There are dwarf forms of Shasta daisies. (perennials)
Dalmation pyrethrum (perennials)
White cosmos would be tall enough to hide foliage (annuals)
