Obedient Plant favors moist, sunny habitats west into Montana, South to Tennessee, throughout the East and North East, and North into Canada. It is called obedient plant for one's ability to twist and turn the flowers and have the flowers conform to their newly faced positions. It is incompatible with most formal landscapes, and would have to be skillfully designed into such a design. The root system consists of a central taproot and lateral rhizomes which are responsible for aggressive asexual spread in open moist to seasonally wet soil. The formation, habit, and color of the plant in flower make it highly attractive to naturalistic designs and prairie/meadow seedings. It brings it's stunning display late in the year, around Cincinnati, usually not until Late August-September. Bumble Bee species (Bombus sp.) are responsible for the bulk of pollination, but the larger species that would rather not squeeze into the flowers, steal nectar by puncturing the flower from the outside to retrieve nectar with out pollinating. This plant is also occasionally visited by Hummingbirds. In a moist-mesic or wet-mesic meadow seeding this is a great plant for late season color and general diversity, but should not be planted or seeded to be a dominant species as it's wildlife value to birds, mammals, and insects is relatively low. Maturing at 2 to 3 feet, this plant is sure to stop any camera bearer in their tracks for a close up in the late summer.
(Tall Coreopsis-Coreopsis tripteris, Full Sun, Moist-Moderately Dry, Naturalistic Only)
The tallest and perhaps most interesting of the American Coreopsis is arguably Tall Coreopsis. Native to wet mesic and dry mesic Mixed Grass Prairies and Tall Grass Prairies, this will compete with bully tall grasses like Big Bluestem and Indian Grass effectively. Tall grasses actually help prop this lanky specimen up, usually reaching a minimum of 4 feet tall, but more commonly over 6 feet tall. The foliage turns an attractive dark red in the fall and the plants look best in mass with at least 3 grouped together within the backdrop of a naturalistic landscape design. In prairie and meadow seedings/installations, plant/seed them randomly as the tall accents will add great vertical interest where ever they land. The coreopsis genus flowers in general are very friendly to a wide variety of pollinators. From short tongued to long tongued bees, butterflies and flies so if planting for ecological value this is a solid pollinator supporter in the hot dry month of August. Tall Coreopsis will also diversify the infrastructure of your prairie or meadow garden. Many insects bore into the stems of such tall forbs and over winter within them, so leaving these up over the winter into spring raises the habitat value of your planting. Don't bother trying to work this plant into a formal design, it's habit is too "free" to conform to such a controlled landscape, which I think adds to it's appeal within naturalistic designs.
