Chrysanthemums (mums) are one of the most popular fall garden flowers (along with pansies).  Most mum plants are easy to grow with their basic needs being full sun, rich soil, good drainage, and good air circulation. There are hundreds of varieties available in a range of shapes and sizes that can provide blooms from late summer through fall. We've chosen the varieties that we think you'll like for the entire season and these are perennials (several varieties are annuals for our zone..7).
