Identification
This stems of this delicate-looking evergreen grow upright to 10 cm tall, from long runners. Short-stalked leaves branch off the stems in opposite pairs. The leaves are egg-shaped or almost circular, firm and leathery, and dark green above but pale below. The ends of the leaves may have a few small teeth. The flowers are the major identifying characteristic, however. As the name suggests, the flowers generally appears in pairs. These pairs of trumpet-shaped flowers nod or droop down from the ends of a Y-shaped stalk. They are pink to white, approximately 1-1.5 cm long, and quite fragrant. This species is actually a shrub in the honeysuckle family.
Habitat & Range
Twinflower is found at all elevations below the tree line. It grows in both shady and open areas, and prefers somewhat dry to somewhat damp habitats. Look for it in the understory of forested areas, amongst other shrubs, and along rocky shorelines. More detailed information about where to find it and associated species can be read on the E-Flora species page.
There are two subspecies of twinflower in BC. Linnaea borealis subsp. longiflora is somewhat more common in BC, and is found throughout the province. L. borealis subsp. borealis is also found in most of BC, except for the northernmost corner of the province. Together the ranges of the two subspecies cover most of North America (click here for range map). The borealis subspecies is also found in Northern Europe.
Similar Species
The two subspecies are mainly differentiated by slight flower structure differences. Linnaea borealis subsp. longiflora has 10-16 mm long, bell-shaped flowers. L. borealis subsp. borealis has 9-11 mm long funnel-shaped flowers.
