Pedicularis canadensis

wood betony [Blooms: Apr-Jun]

Wood betony's numerous yellow (less commonly, reddish brown) flowers arise from a spike (raceme) at the apex of the stem; the blooms open in a wave from the base of the spike to its tip. The flowers tend to be twisted clockwise around their long axis by about 30° so that, viewed from above, the flower spike looks like a pinwheel. Individual flowers are 1/2-1" long, tubular, with a hood-like upper lip that curves down into two small "teeth" or "fangs" at its tip (a distinguishing character of this species) and a paler or white three-lobed lower lip that functions as a landing pad for pollinators. The four stamens are hidden under the upper lip of the corolla; they are of two lengths with light yellow anthers. The single style is also largely hidden under the upper corolla lip, although the tip of the style may protrude; the stigma looks like the head of a common pin. The fruit is a 1/2" long, angular capsule reminiscent of a shoe tree (as in footwear, not plants) that is initially green, turning brown as it matures.

Wood betony is a native wildflower that is a hemiparasite, i.e., it is partially dependent on the roots of neighboring plants for water and nutrients, typically the roots of asters, grasses, and oak trees. Wood betony is a small plant (6-12" tall) that initially consists of a dense rosette of basal leaves each up to 6" long and a third as wide. A stout green or reddish-brown stem 3.5" long and covered with long, fine white hairs subsequently emerges from the center of the basal rosette. Small leaves with alternate insertions cover the stem; these stem leaves are oblong or lance-shaped with multiple deep pinnate lobes that have rounded, symmetrical teeth and long hairs along the leaf margins.
