Collinsia bicolor

This is a pleasant little wildflower suitable for a wild woodland garden. Foliage is rather coarse, but the flowers have a delicate beauty. I would not say it bloomed terribly long - early June to early July here for me in Wisconsin (from wintersown seeds). Foliage died down after bloom in late summer. I did not think it was too spectacular - would probably not plant it again.

Easily grown and graceful, Collinsia bicolor is popular for its long flowering season. The slender stems, up to 2 ft (60 cm) high, carry opposite pairs of lance-shaped midgreen leaves below loose clusters of showy bicolored flowers with white upper lips and lilac to pinkish purple lower ones.The many snapdragon-like flowers are 1 to 2" long with oblong leaves held in tiers at the top of 1 to 2 foot tall, somewhat hairy stems and is self sowing
Collinsias are suitable for growing in mixed borders and annual beds.
They can also be grown in pots on a windowsill.
