Yellow wildflowers of west and southwest USA: Linaria vulgaris: common toadflax, butter-and-eggs, yellow toadflax: Plantain family (Plantaginaceae). ColoradoView – Invasive Hybrid Toadflax Species Distribution Modeling Project Final Report May 12th, 2016 1. Dalmatian toadflax, a widespread weed in North America, was introduced from the steppes of its native Eurasia in the late 1800s. One species, Calophasia lunula is effective if used in an integrated weed management program. Habitat: I spotted this plant in a meadow - this was the last one left as I had noticed at least 6 Linaria vulgaris plants in this area during the month of September. Spike-like raceme 3 to 6 inches long of irregular yellow and orange flowers, each ¾ to 1 inch long. Yellow toadflax can reproduce both by seeds and vegetatively. From seed distribution to creeping root systems, yellow toadflax can aggressively form colonies. The Toadflax grows wild in most parts of Europe, on dry banks, by the wayside, in meadows by hedge sides, and upon the borders of fields. Individual plants can live up to five years. Prefers sandy soils but often invades fields, grasslands, roadsides as well as open forests. These colonies can push out native grasses and other perennials, thereby altering and simplifying the species composition of natural communities and reducing forage production for livestock and wildlife. Repeat applications are necessary to achieve control. Habitat and Blooming Times The flowers, which are distributed around the raceme, were about 3 cm long and consisted of a tubular corolla with a pale yellow upper lip and an orange-yellow lower lip. Y appear as early as March. Yellow toadflax typically emerges around mid-April. The plant decreases forage for domestic livestock and some big game species and decreases habitat for … Habitat Grasslands, pastures, agricultural fields, and roadsides infested with yellow or Dalmatian toadflax. The key to controlling yellow toadflax is to destroy seedlings that emerge from the soil seed bank, limit vegetative spread of colonies, and maintain a cover of native perennial plants to discourage future infestations. In Adams County, yellow toadflax infestations can be found along the South Platte River, along Clear Creek, and in various lakes and ponds. Yellow Toadflax can displace existing plant communities and desirable plants, cause loss of forage for domestic livestock and some big game, and reduce habitat for associated native animals.

This should be done before seed-set and repeated as long as there are viable seeds in the soil (up to ten years). It is still sold today in nurseries and seed catalogs as "Butter and Eggs" or "Wild Snapdragon". Mowing will reduce the year's growth and reduce the amount of seed set, but is not an effective option for long-term control. Linaria vulgaris (commonly known as yellow toadflax) is a creeping perennial forb, with bright yellow and orange snap-dragon-like flowers.

Watch out for fill dirt and landscaping soils, also another means of dispersal for toadflax seeds into uninfested areas. Be sure to check and clean your hiking boots, vehicle/bike tires, pet fur, livestock fur, farm equipment, and construction equipment thoroughly before leaving a toadflax infested area. Habitat Although this plant prefers well-drained, coarse-textured soils that can range from sandy loams to heavy clay to coarse gravels, it actually grows better when in moist, fertile soils. It is especially abundant in sandy and gravelly soils, and in chalk and limestone districts, and avoids acid soils.
