Linaria purpurea grows wild along the roadsides here in New Zealand. It is a very hardy, self seeding, pretty plant.

Good cut flower. Reblooms beautifully after deadheading. Fills in its space nicely. Flowers are small, so they need to be enjoyed up close; plant it close to the edge. Self-seeds nicely, not aggressively for me.
