Identification and Information

Pedicularis lanata, commonly known as woolly lousewort (Inupiat: Ipchuk), is a short perennial herb that grows 5-30 cm tall from a starchy, thick yellow, branching taproot and caudex but no underground stem. The aerial stems are simple (unbranched) and erect. Flowering stems (and the entire plant) are often dense, white-wool hairy. It has numerous pinnately compound, narrowly lanceolate basal leaves. The basal leaves form a fern-like tuft. The stem leaves are similar but shorter than the basal leaves, alternate, and dye annually. The leaves may be petioled.

The inflorescence is a terminal spike of numerous, densely packed flowers and is densely woolly. The flower pedicels emanate from the axils of the stem leaves. The flowers have green bracts similar to the leaves, reduced upwards. The flowers are bilaterally symmetric and pink to lavender. The corolla (petals) is 5-20 mm long, two- or three-lobed, with a helmet that is not prolonged into a long beak and absent teeth. The calyx (sepals) is 4-5 mm long with five triangular teeth about 1 mm long. The flower has four stamens with long, hairy filaments. It has a single style, 20-24 mm long, with one superior ovary. The fruit is an egg-shaped capsule 8-13 mm long, and the seeds are yellowish and 2-3 mm long.

The dense, woolly hairs that encapsulate the flowers of Pedicularis lanata serve a dual purpose. Primarily, they provide critical insulation, protecting the reproductive structures from the harsh, cold climates where the plant thrives. Additionally, this woolly covering helps to trap moisture around the flowers, mitigating the drying effects of wind and low humidity typical of its alpine and tundra habitats.

Its common name, woolly lousewort, is due to the dense wool covering the plant, but it is less frequently known as the bumblebee flower because it relies on the bees for pollination early in the growth season.

For information only (typically historical) – I take no responsibility for adverse effects from the use of any plant.

Pedicularis lanata has numerous traditional, medicinal, and culinary uses. Most commonly, the root is boiled, roasted, or eaten raw and tastes somewhat like young carrots. The Inupiat eat the fermented flower topped with oil and sugar, like sauerkraut. The stems can also be boiled and eaten as a potherb.

People of the Great Slave Region in the Northwest Territories would dry small pieces of the root to mix and smoke with tobacco to relieve headaches. Flora of Dempster Country lists other potential medicinal uses, but I have not verified those with any other sources, so you can check the link here.

Distribution and Habitat

Map data from the Global Biodiversity Information Facility (GBIF), NatureServe Explorer, and Kew

Pedicularis lanata is widely distributed throughout Alaska, particularly north of the Alaska Range, and extends across northern Canada, including British Columbia and Alberta. Its range also encompasses Greenland and extends to eastern Siberia. While some references suggest its presence in Montana, primary sources like GBIF and NatureServe do not confirm this, and thus, it is not included in my distribution map.

Woolly lousewort lives in habitats from wet muskeg to dry, rocky alpine meadows and from flood plains to sandy and silty soils. It is commonly found on mesic to dry rocky slopes, ridges, and grassy tundra within the alpine zone. The plant is remarkably tolerant of various environmental conditions, often growing on substrates such as hummocks, river terraces, tundra, and dry meadows.

We found one of these plants pre-bloom on the Elliot highway in mid-June at lower elevation at the edge of a burn.

Awesome! Do you happen to know the approximate elevation or location and date? I’d like to add more information about blooming times to these pages and the more information the better! I typically see them in full bloom by early June, but that’s usually at higher elevations, alpine tundra in full sun. Thanks for sharing Margie!
