Comprehensive Description

Read full entry


This native perennial plant is up to 2' tall and sometimes bushy. The stems are covered with conspicuous white hairs. The sessile alternate leaves are up to 3" long and 1" wide, lanceolate or ovate, with smooth to slightly dentate margins. They are pubescent on both the upper and lower surfaces. The inflorescence at the top of the plant consists of a short cluster of flowers or hairy buds. These flowers are bright yellow and individually about 2" across. Each one has four large petals, large showy stamens, and fine white or transparent lines that radiate outward from the center of the flower. These lines function as nectar guides, and are more visible to insects than humans in the ultraviolet spectrum. The blooming period occurs during late spring or early summer and lasts about a month. The flowers bloom during the day and have a pleasant fragrance. The seeds are without tufts of hairs, while the root system is highly rhizomatous. In disturbed areas, colonies of plants are readily formed. The new growth during early spring and older foliage during the fall often acquire reddish tints. Cultivation
