Baptisia, or false indigo, is a popular spring-flowering, bushy perennial that grows 2 to 7 feet tall and wide depending on the species. There are white-, purple-, and yellow-flowered types available.
Now for a different look in baptisia comes 'Twilight Prairie Blues'. Bred at the Chicago Botanic Garden, this new variety features copper-purple flower spikes with a lemon-colored keel on the petals. Baptisia is a vigorous, native perennial with blue-green foliage that is hardy to USDA zone 4 and grows to 3 feet tall and wide at maturity. It grows in part to full sun and tolerates the summer heat well.
