Dalmatian Toadflax (Linaria dalmatica)
Dalmatian toadflax is a member of the Figwort family.  It was introduced as an ornamental from Europe, and is now rapidly invading dry rangeland from 5,000 to 8,000 feet.  Dalmatian toadflax is still quite rare in Pitkin County, but it is very common in Glenwood Springs.  It has been found along the Capitol Creek and Snowmass Creek drainages.  It is a creeping perennial that closely resembles yellow toadflax.  However, unlike yellow toadflax, Dalmatian toadflax has waxy, heart-shaped leaves that clasp the stem.  The stems grow to 2-4 feet in height.  The flowers are snapdragon-shaped, bright yellow, with orange centers.  Dalmatian toadflax is especially well-adapted to arid sites and can spread rapidly once established.  Because of its deep extensive root system, waxy leaves, and heavy seed production, this plant is difficult to manage.
