Botanical Name

Plant Common Name

Screamin' Yellow Baptisia, Yellow False Indigo, Yellow Wild Indigo

General Description

A prized selection of wild indigo, 'Screamin' Yellow' is a large perennial noted for its yellow pea-like flowers and yellow-green leaves. Descended from a native perennial of the southern United States, 'Screamin' Yellow' flowers in the springtime on tall, unbranched, leafy stems. A mature plant can send up dozens of stems, each topped by ten or more flowers, one above the other. Various butterflies visit the flowers. The tan or brown seedpods that follow the flowers are also an ornamental feature.

Yellow wild indigo needs a full sun location for best form and flowering, but will grow in partial shade. This perennial tolerates drought and nutrient-poor or gravelly soils. It generally will be successful in any average, well-drained soil. Use this perennial as a specimen or a small grouping in a border or in a meadow among other wildflowers and ornamental grasses. To keep the plant in a mounded shape, lightly trim after flowering. Often the dried seeds are used as decoration in dried flower arrangements. Try not to disturb the roots once the plant has established itself.
