Dalmatian Toadflax
Linaria genistifolia

Dalmatian toadflax is a perennial, up to 3' tall, reproducing by seed and underground root stalks.  Leaves are dense, alternate, entire, upper leaves are conspicuously broad-based.  Flowers are borne in axils of upper leaves and are 2-lipped, 3/4 to 1 1/2 inches long with a long spur, yellow with an orange, bearded throat.  Fruit is a 2-celled capsule with many irregularly angled seeds.  Flowers appear mid-summer and continue to flower until early fall.  Leaves individually clasp the stem.

It is aggressive and can be found along roadsides and on rangeland where it can become a serious problem by crowding out desirable forage.  An extensive and deep root system along with a waxy leaf make this an extremely difficult plant to control.
