Alaska Indian Paintbrush
Castilleja unalaschcensis
Alaska Indian Paintbrush (Castilleja unalaschcensis) is a perennial wildflower found in Alaska and western Canada. The plant grows to a height of 2-3 feet and is characterized by its dark green leaves and bright red bracts in mid-spring. Alaska Indian Paintbrush is a hemicryptophyte, meaning it grows from a perennial caudex or stem, which allows it to survive cold Alaskan winters. This plant is symbiotic with nitrogen fixing bacteria, allowing it to thrive in poor soils. It is a favorite of pollinators such as honeybees, bumblebees, and hummingbirds. The vibrant blooms make it a popular choice for flower beds and wildflower gardens.
