Rudbeckia amplexicaulis (Annual)
Rudbeckia amplexicaulis also called clasping coneflower because its leaves hold the stems. It is an annual native from Georgia to Texas, north to Missouri, and Kansas. This small-flowered glabrous composite resembles a Mexican hat in a flower shape and typically grows 18-24” tall. Beautiful flowers feature columnar dark brown center disks, each with 5-10 drooping yellow ray flowers, which may have orange or brownish-purple at the ray bases—blooms in summer. Oblong to ovate leaves are toothed to the entire and clasp the stem.
It is an annual that is quickly grown in average, dry to medium, and well-drained soils in full sun. Perhaps best in moist, organically rich soils, it will tolerate light shade. It also tolerates heat, drought, and a wide range of soil conditions except for poorly-drained wet ones. Deadhead spent flowers to encourage additional bloom and to prevent any unwanted self-seeding. Will remain in the garden through self-seeding.
