Helenium linifolium is a North American perennial plant in the sunflower family, commonly known as slimleaf sneezeweed. [1] It is found only in southern Texas. [2] [3]
Helenium linifolium is an annual herb up to 80 cm (32 inches) tall, with wings running down the sides of the stems. Leaves are long and narrow, almost thread-like, merging with the wings on the stem. One plant can have 100 or more small spherical or egg-shaped flower heads. Each head has up to 500 disc flowers, each yellow-green toward the bottom but brown or purple toward the tip. There are also 8-9 red or yellow ray flowers. [1]
