What's in Bloom

It’s time to say good-bye to home-grown tomatoes and bring out the rakes. Autumn is here along with cool-weather crops and a hint of fall color. The last perennials to begin their blooms include monkshood, autumn crocus, Tatarian asters, toad lilies and Ozawa onions. Only a few true asters remain in bloom in the prairie and along the shorelines. Displays of annuals include chrysanthemums, cultivated asters, pansies, kale and tropical salvias that don’t mind a few degrees of frost.  Roses and tropical waterlilies are hanging on until a hard freeze, but will not produce new buds.  If you are chilly, come see what’s new in the greenhouses. Enjoy autumn at the Chicago Botanic Garden.
