Similar to R. maxima except that it is hairy (R. maxima is glaucous) and it has relatively smaller leaves and heads. It is similar to R. grandiflora which has diskflowers less than 4 cm long in fruit, while R. texana has disk flowers that are 4-8 cm long in fruit. The lower leaves of R. texana are 16-25 cm long by 6-8 cm wide and often triple nerved below. Leaves lustrous, blades narrower. Achene not with 4 nearly equal facets.
Easily grown from seeds collected in the fall when the cones become loose. Seeds germinate with no treatment in 1-2 weeks. Steffen (1997) recommends cold/moist or dolc/dry stratification, possiably to break dormancy induced by long term storage. Plants bloom the first year from seed. Clumps divided in late winter or early spring should be dusted with a fungacide and the foliage cut back to reduce transpiration. Seeds average approximately 25,000/lb.
Attracts birds and butterflies.
This species occurs infrequently, primarily in coastal prairie, in Louisiana and southeast Texas. Restricted to Louisiana and Texas (USDA 1998). The Acadian name for all of the yellow coneflowers is "marguerite" (Holmes 1990).
