Planting other things in the iris bed?
How far can I go in planting other items in my iris bed? I have a few spring bulbs on the edges, and just a couple perennials. I just realized I need to plant poppy seeds like NOW. Can I sprinkle the seed right in among the irises? It would be easy b/c there's already no grass there and it would be nice to have something there blooming later in summer. However, I don't want to do anything that's bad for the irises. Thanks!
