Sticky Snakeweed
Gutierrezia microcephala
About Sticky Snakeweed (Gutierrezia microcephala) 0 Nurseries Carry This Plant Gutierrezia microcephala is a species of flowering plant in the daisy family known by the common names sticky snakeweed, threadleaf snakeweed, threadleaf broomweed, and smallhead snakeweed. It is a subshrub native to the southwestern United States and northern Mexico, and can be found in arid grassland and desert sand dune habitats. It can be toxic to livestock in large quantities, due to the presence of saponins and high concentrations of selenium. Gutierrezia microcephala is a small, resinous, perennial desert subshrub that is typically 20 to 60 centimetres (7. 9 to 23. 6 in) in height and less than 100 centimetres (39 in) in diameter. It is heavily branched, often causing it to be nearly spherical. New shoots and twigs are green to yellow in color, and older parts are brown and woody. The leaves are linear, threadlike, and alternate; 1 to 4 centimetres (0. 39 to 1. 57 in) long and 0. 5 to 2 millimetres (0. 020 to 0. 079 in) wide. Along with the leaves, the stem tissue is photosynthetic, giving the plant a high photosynthetic capacity. G. microcephala typically flowers July to October, but this can vary depending on the amount of precipitation. Gutierrezia microcephala, a native North American plant, is found throughout the southwestern United States (from California east as far as Texas and Colorado) and northern Mexico (from Baja California to Tamaulipas, Veracruz, and Zacatecas). It occurs in a variety of ecoregions, such as arid grasslands, chaparral, sand dunes, and oak or oak-pine woodlands. G. microcephala is primarily found in well-drained sandy, gravelly, or rocky soils, and is often found in intermittently dry creeks or on the adjacent slopes. It often predominates on shallow, rocky soil, where grasses are not well established.
