Smooth CamasZigadenus elegans Pursh
This tall perennial has fragrant flowers with a foul smell that attract mainly small flies and gnats as pollinators. Plants can sicken livestock, are poisonous to humans, and may be fatal if eaten. They lose their aboveground parts in the fall, over-wintering as a bulb. Although they are common in the prairies, plants in more western locations can grow at high altitudes up to 3600 meters.
Canadian Rarity Status:
Not rare. Listed as “may be at risk” in New Brunswick.
Several long, grass-like leaves occur in a basal tuft, have smooth edges, and a keeled midrib. Flowering stems grow 20-80 cm tall, with a few small leaves, and are topped by an open cluster of 1-50 stalked, saucer-shaped flowers. Each of these has six egg-shaped tepals with a dark green heart-shaped gland, a 3-parted stigma and six prominent yellow anthers. Fruits are egg-shaped capsules containing numerous small seeds.
