The floral collar is divided into two concentric zones of different colors, a bright yellow border surrounding a central orange-yellow zone.
The leaves are oval and pointed, slightly serrated along the edges, and appear in basal tufts. The stem leaves are smaller and sessile (without petioles), with a rounded, cordate base; their color is a bright, light green.
👨🌾 GARDENING TIPS👨🌾:
-
- Easy to grow as an annual, this short-lived perennial quickly forms a medium-sized clump that readily self-seeds.
- It prefers full sun and is content with ordinary, fairly fertile soil, which is fresh to occasionally dry.
The Tales:
All Rudbeckia species are dye plants (especially R. hirta and R. laciniata) due to the presence of flavonols in their tissues. The inflorescences used alone give orange-yellow colors, while the entire plant provides yellow-green shades.
It is a cultivar derived from Rudbeckia hirta, a short-lived perennial native to the United States.
In the wild in the US, this plant grows in prairies, pastures, and cultivated fields, where it is considered a weed.
The genus name honors Olof Rudbeck (1630-1702) Swedish botanist and founder of the Uppsala Botanic Garden in Sweden where Carl Linnaeus was once a professor of botany.
The species name of hirta means “hairy”, a reference to the short bristles that cover the leaves and stems.
