Description

Rudbeckia triloba is a beautiful perennial that forms a very bushy plant with highly branched stems bearing dark green leaves that are single or divided into 3 lobes. It bears dazzling yellow flowers that are quite round. They display a black conical centre, which has earned it the nickname of brown-eyed susan. This slightly wild-looking species blooms abundantly if planted in full sun in moist soil.

 

This genus comprises annual and perennial plants, which are almost irreplaceable in a summer garden.
