Late summer in Michigan features a host of blooming plant species. Late summer is an especially good season for native Michigan plants, many of which appreciate the long days, high humidity and warmest weather of the year.
Sunflowers are a well-known and popular late-summer flower and food crop. A number of sunflower species are native to Michigan. These include the woodland sunflower, prairie sunflower and the pale-leaved sunflower. Plant sunflowers in early June and in full sun to partial shade.
Both the rough blazing star and marsh blazing star are Michigan natives that bloom in late summer, producing a tall shoot of densely packed flowerettes, usually purple. A native Michigan perennial, blazing star will grow up to 5 feet tall once established. It prefers full sun or partial shade.
Chrysanthemums, or "mums" for short, begin blooming in late summer and continue until the first frost. Available in a wide variety of colors, most chrysanthemums will survive a Michigan winter if they are well insulated with mulch and temperatures are not unusually cold. After first frost, cut chrysanthemum foliage back to an inch or so above ground level, then cover with straw or leaves. Uncover chrysanthemums at the end of March, or when the snow cover has melted.
