Linaria canadensis (common name: blue toadflax)

Propagation: Seed - sow spring in situ[1]. An autumn sowing can also be made in areas with mild winters[1]. This sowing will produce larger plants.

Cultivation: A very drought resistant plant once established, it thrives in a poor gravelly soil[1]. Nitrogen-rich soils produce excessive leaf growth at the expense of flowering[1]. Prefers a sunny position[1].

Range: N. America - Nova Scotia to Florida, west to Minnesota, Oregon, Texas and California

Habitat: Dry sterile or sandy soils, often a weed in sandy loams[2].

Medicinal: The leaves are antihaemorrhoidal, diuretic and laxative[3][4]. They are applied externally in the treatment of haemorrhoids[4].

Soil: Can grow in light and medium soils.

Drainage: Prefers well drained soil.

Flower Type: Hermaphrodite
