Last fall I prepared a border bed along a Privet hedge running the length of my front yard. It gets full sun ALL day.. I want a colorful selection of blooms.. I am partial to reds, purples and pinks.. Not terribly fond of yellows and whites. I would like something that stays compact.. probably no more than a foot high. I was thinking of Vinca as it comes in the colors I like and loves sun. Any other suggestions?
