It's hard to believe you could find a place like Rockwoods Reservation in busy west St. Louis County. But it's a sample of the Ozarks right in the middle of the suburbs.
Fleshy, showy, perennial plants to 2 feet tall, often in large groups. Flowers many, in loose clusters, terminal, hanging like bells, about 1 inch long. Buds pink, turning to light blue on opening. Pink forms are not rare; a white form exists. Blooms March–June. Lower leaves are long, tapering into stems, broad, ovate, to 5 inches long. Stem leaves are smaller, elliptical. All leaves are bluish-green. This is the only Missouri member of the borage family that is not hairy.
