Toadflax (Common/Yellow) is a perennial that spreads by seed and creeping roots.
Perennial weeds grow from root stalks year after year. Perennial weeds spread by seeds and roots, and therefore the entire plant must be destroyed.
Classification: Noxious Weed
Stem: Often several stems forming dense patches, unbranched to few branches in upper stem, hairless, up to 1 meter tall
Leaves: Alternate to spirally arranged, numerous, attached directly to the stem, hairless, margins smooth or entire, linear, up to 10 cm long
Flowers: Resemble Snapdragon, bright yellow with yellow-orange throat, up to 3.5 cm long including the spur extending from the base, alternately arranged along terminal ends of stems
Distinguishing Toadflax (Common/Yellow) from Leafy Spurge and Dalmatian Toadflax
Toadflax is commonly confused with Leafy Spurge when flowers are absent. However, Yellow Toadflax is easily distinguished by the absence of milky juice in the plant. Also confused with Dalmatian Toadlflax, but easily distinguished by the presence of long linear leaves compared to the short broad leaves of Dalmatian Toadflax.
