Arethusa bulbosa Linnaeus. Common name: Dragon's-mouth, Bog-rose, Arethusa. Phenology: May-Jun. Habitat: Sphagnous bogs and seepage swamps. Distribution: NL (Newfoundland) and NL (Labrador) west to SK, south to NJ, DE, IN, and MN, and to NC and SC in the mountains, rare south of ME, MI, and MN.
ID notes: The lanceolate, plicate leaf (15-30 cm long, 2-4 mm wide) usually emerges after flowering, the flowering plant thus normally consisting (aboveground) of the solitary scape only. The lip is crested with fimbriate ridges, marked with yellow and purple.

- If you opt out of including email, please be as specific as possible (e.g., which photo is incorrect?)
- Please do not submit questions asking to identify plants or about horticultural topics (e.g., how do I control an invasive plant in my garden?). Instead, those questions can be submitted here for the Carolinas region only.
- Please do not send us feedback about unkeyed species as this work is ongoing.
- Please allow time for flora edits to show in our next data release. We greatly appreciate your feedback but may require extra time to research complicated taxonomic issues.
Horticultural Information
Intro: Scapose perennial found in sphagnous bogs and seepage swamps.
Stems: Stem a leafless scape (with a few bracts) arising from a bulbous corm before the solitary leaf emerges.
Leaves: Leaf basal, developing during and after flower opens, linear, obscurely pleated; there are several sheathed bracts on the flower scape as well.
Inforescence:
Flowers: Flower solitary (rarely 2), terminating the scape, pink to magenta (rarely white), 1-2 in. long, bilaterally symmetric and consisting of 3 erect, narrowly oblong sepals rising above the upper 2 arched, hood-like petals and a drooping, elongated, white and pink lower "lip" petal with purple-streaks and and a tufted, yellowish crest.
Fruits: Fruit an erect, ellipsoid capsule.
Comments:
Height: to 14 in.
