Phonetic Spelling:lah-POR-tee-ah kan-ah-DEN-sis

Genus:Laportea

Species:canadensis

Family:Urticaceae

This upright, perennial herb is characterized by its prominent stinging hairs. The leaves are arranged alternately, are simple in structure, and have coarse teeth along their edges. The flowers are small and not very noticeable, typically found in clusters in the axils of the leaves.

It thrives in forested or natural environments, particularly in rich woodlands and the moist lowlands adjacent to rivers and streams.

EDIBLE PARTS: The young shoots can be consumed as a potherb. Boiling them eliminates their irritating properties, making them suitable for inclusion in stews or soups. HARVESTING GUIDELINES: Only gather young shoots from locations that you are certain have not been treated with pesticides. The best time to collect these shoots is in the spring. It is advisable to wear gloves during the collection process, as the shoots can cause a stinging sensation. SAFE HANDLING INSTRUCTIONS: Rinse the young shoots in warm water to eliminate any dirt or debris, avoiding the use of dish soap or sanitizers, as these can leave harmful residues. Using kitchen tongs, place the shoots in a pot of boiling salted water and cook for five minutes. They can then be served as a vegetable or added to soups, with the stinging effect dissipating once cooked. SOURCE: Crowhurst, A. 1972. The Weed Cookbook. Lancer Books, Inc. New York, 190 pp.

Laportea canadensis Feature Summary

Attributes
Central & East Canada to Mexico
This is a larval host plant for butterflies. The Eastern Comma (Polygonia comma) appear as overwintered adults from spring until the end of April and they lay eggs. The summer form emerges from May-September and lays the winter form. These adults appear in September and find a location to overwinter for the next year. Red Admiral (Vanessa atalanta) have two broods from March-October, they overwinter from October-March in southern Texas.
