Description
 
 

Wood lily is a 12 to 36 tall, erect, hairless, unbranched perennial rising from a chunky bulb.

The leaves are scattered, more or less alternate, except the uppermost, which are in a whorl. They are stalkless, 2 to 4 long, lance-shaped, and taper to a sharp point. The tips droop when the sky is overcast, and ascend in the sun.

The inflorescence is a terminal cluster of flowers arising from a single point at the top of the stem. There may be 1 to 5 flowers, but there are rarely more than 3.

The large flowers are 2½ wide and are not fragrant. They are widely bell shaped and erect—they do not hang downward. They consist of 6 distinctly clawed tepals, 3 inner tepals (petals) that are similar in appearance but somewhat wider and shorter than the 3 outer tepals (sepals). The tepals are spoon-shaped and narrow to a slender, stalk-like base (claw). They are erect and flaring, and bend backward slightly toward their tips. They do not touch near the base. They are bright orange or reddish-orange with a yellow throat and purple spots near the throat. The tips come to a blunt point. The stamens equal or project beyond the tepals.

Similar Species

 
 

Michigan lily (Lilium michiganense) is much taller, 3 to 6 at maturity. The leaves are whorled except near the top, where they are single, in pairs, or in partial whorls. The flowers are 2½ to 3 wide, Turk’s-cap shaped, with tepals that bend backward to their base.

Orange daylily (Hemerocallis fulva) is taller, 2 to 4 at maturity. It has a basal rosette of grass-like leaves and no leaves on the flowering stem. The flowers are up to 4 wide, semi-erect or horizontal, funnel-shaped, tannish-orange with a yellow throat and a red stripe. They do not have spots near the throat. They last only one day.

Tiger lily (Lilium lancifolium) has a central stalk that is densely covered with long, tangled, white hairs, especially near the top. The leaves are alternate, even at the top of the stem. The inflorescence is a terminal, branched, elongated, cluster of 3 to 6 flowers, not an umbel. The flowers hang downward at the end of stout, widely spreading flower stems. They are Turk’s-cap shaped, up to 4 wide and uniformly orange to reddish-orange—they do not have yellow or yellowish throats. They have purple-brown spots except near the tips, not just near the throat. They last more than one day.

The Wood lily is fairly common up here, living in many of the roadway ditches. I have quite a few growing on my property.

About

Published on Jul 3, 2013

A Wood Lily growing by the Kicking Horse River in Yoho National Park. The Wood Lily also goes by the names of Philadelphia Lily, Prairie Lily, Western Red Lily, or Mountain Lily. It is native to North America and can be found in many parts of Canada and the United States. The plant is threatend, endangered, or extirpated in many parts of the continent because of people picking the flower. The picking of the plant results in non-renewal for the bulb the next season. A variant of the species, the Western Red Lily (L. philadelphicum andinum) is the provincial flower of Saskatchewan.
