Here is a nice late spring combination: giant allium and 'husker red' penstemon. The allium bring out the subtle purple streaks of the penstemon while the penstemon provide the perfect backdrop for the allium. It is important to consider texture and shape as well as color when choosing plant combinations. I like the contrast of a bold plant against a more delicate one. They aren't competing for attention but compliment each other nicely. These are planted adjacent to a patio but they would also look great from a distance in the garden. If you're going to use allium, don't skimp, they tend to get lost if there are only a few. When used in a group though, their whimsical shape is unmatched by any other flower.
