I currently have these scattered all over two pretty large raised beds; they all promptly came up even in our lackluster and wet PNW spring. They seem hardy but pose no threat to taking over the space. In a few places they are already being more or less smothered by my tomato plants, and I'm totally ok with that. I want them for their companion planting benefits and for some extra color and interest in the empty spaces. They do a good job of peeking through and finding room for themselves without being a nuisance to my edibles.
