Garden Club — What Are the Best Flowers to Plant in Colorado?

Nothing screams warmer weather than a yard full of flowers. The best approach is to make sure that you are combining flowers that have staggering bloom times. Couple a few all season perennials with mid-summer to fall perennials and add some great hardy annuals with various bloom times to create an all-season flower garden that will bring a visual paradise.
