Toadflax

Linaria vulgaris ( Butter & Eggs )
A rhizomatous perennial, reaching up to 3.3 x 1 foot, that is a widespread native of Europe and northern Asia where it is often found on roadsides and sand dunes. While I find it to be too beautiful to call a weed, it can become invasive on some sites. It is locally naturalized in eastern North America to as far north as Fairbanks, Alaska; southwest Yukon; Edmonton, Alberta; Ignace, Ontario; Chapleau, Ontario and Ottawa.
The linear leaves, up to 3 x 0.1 inches in size, are blue-green to mid-green.
The yellow flowers, up to 1 inch long, are borne late spring to mid-autumn. Linaria purpurea ( Purple Toadflax ) is similar except with pink or purple flowers.
Hardy zones 2 to 8 in full sun on sandy, well drained soil. It is very drought tolerant. Propagation is from division or seed sown during spring.
