Bush Sunflower Among Top Four Forbs on Rangeland

Bush Sunflower rarely seen on rangeland in our area, with the exception of the lonely one growing within an existing ‘bush’ such as skunk brush or any other low growing bush that protected the highly palatable bush sunflower form being grazed to ‘death’. Although the leaves and stems feel very harsh being somewhat scratchy and not being a particularly showy or pretty ‘weed’, livestock and wildlife alike readily graze it. Being a perennial plant having 26% to 31% protein in the early spring, its robust root system makes it a drought tolerant plant that can be an unbelievably valuable resource for rangeland health and the ranchman’s pocketbook. (A very opportune time to have a high protein source of forage available coming out of winter months.) The assumption that the bush part of the name was derived from its tendency to be found growing within a bush, is supposedly incorrect, as given the opportunity to flourish within a good grazing program it is said to develop a bush like appearance. (Still waiting to observe this.) As time goes by, on rangeland protected by a good graze-rest program, the plant is becoming ever increasing in prevalence like the one pictured below, without the ‘bush’ being present. (Young mesquite in picture being excepted) Areas that are under a continuous grazing program seldom have bush sunflower present other than those growing in a bush as referred to above. When numerous bush sunflowers are present, it is an excellent indicator of improving rangeland health.
