Description
The sunflower giant is a tall, erect, native perennial forb that grows on unbranched hairy stems from 1 to 3 meters. The stems may be reddish, the hairs spreading, but some plants may have few hair or none and may have only reddish tints on the stem. Helianthus species are quite variable, so it is difficult to determine the specific species of sunflower giant.
