Kleberg bluestem grows as a bunchgrasses, with culms ranging from 8-40 inches in height. Leaf sheaths are 1.25 to 1.5 inches long, generally hairless, and leaf blades are 1.25 to 12 inches long and narrow in width. The inflorescence is comprised of a central stem with 2-15 racemes (flower branches) bearing numerous pairs of spikelets (flowers) along the central axis of the racemes. These grasses are characterized by a high density of reproductive shoots. Fast springtime growers and mature quickly
Native Lookalikes: Currently no information available here yet, or there are no native Texas species that could be confused with Kleberg bluestem.
Ecological Threat: When escaped from cultivation in pasture, can invade and outcompete native grasses in bluestem coastal prairie communities.
Biology & Spread: Prolific seed producers. They begin flowering in the spring, and seed in the summer. Seeds are readily transported by wind.
History:
U.S. Habitat: Thrive under grazing conditions and require full sunlight. Have low tolerance to acidic soils and high tolerance to drought and cold.
Distribution

Management
If the plant is less than two meters tall, hand pulling may be possible. Use a foliar or cut-culm treatment of 1.5% or 27 - 40% glyphosate, respectively.
