Clients often stop in and request a list of perennial bloom times. It’s common for gardeners to plan for the upcoming year. Knowing the times when your perennials bloom helps create a design with color during each season.

Remember, beauty in the garden isn’t all about flowers. We encourage gardeners to consider how plants look when not in bloom since they’ll look that way for some of the growing season. Achieving a diverse garden of year-round interest means giving equal consideration to attractive foliage, texture, growth habit, and wildlife value.
