Dalmation Toadflax
Information | Images
Linaria dalmatica
Short lived perennial
Identification and management tips
- Flowers are bright yellow snapdragons arranged at the top of the stems.
- Leaves are bluish-green with a waxy coating, heart-shaped and close to the stem.
- Dalmatian toadflax has an extensive root system, but can be contained by hand pulling or digging up the roots for an average of 6 years. This depletes the root reserves on small patches, and prevents further seed production.
- For large infestations, where digging is not practical, apply herbicides in the fall. Herbicide success can be variable at best.
