Description
P. canadensis is a perennial forb/herb/subshrub of the Scrophulariaceae family native to North America and Canada.[1]
The stems are unbranched and up to 20 cm tall. The peduncle is pubescent and the rachis is tomentose. Leaves are deeply dissected, pinnately lobed, 5-15 cm long, 1.5-5 cm wide, and mostly clustered at the base of the stem. They have an alternate arrangement, elliptic shape, and serrate margin. Flowers are borne in dense heads, two-lipped, 2 cm long, and 0.5 cm wide. The corolla is yellow or shaded with lavender with capsules that are 12-16 mm long. The capsule is 1 cm long and enclosed by green sepals. Seeds are about 10 per capsule, 5 mm long, with a brown color.[4][3]
Distribution
This plant ranges from Maine, Quebec, and Manitoba, south to northeastern and Panhandle Florida, Texas, and northern Mexico.[3]
Ecology
Habitat
P. canadensis proliferates in moist to dry forests and woodlands and streambanks.[2] Specimens have been collected from loamy sand in hardwood forest, border of swamp area, and magnolia-beech-oak woods.[5]
Phenology
P. canadensis flowers from April through May and fruits from May through July.[3]
Fire ecology
P. canadensis is not fire resistant, but has a medium fire tolerance;[1] despite this, populations have been known to persist through repeated annual burning.[6]
Pollination
P. canadensis is visited by leafcutting bees from the Megachilidae family such as Osmia collinsiae.[7]
