Douglas' Meadowfoam

Limnanthes douglasii R. Br.

Brief Summary

provided by EOL authors
Limnanthes douglasii is distributed in California and southwest Oregon. The California distribution is defined by the North Coast, North Coast Ranges, Cascade Range Foothills, central Sierra Nevada Foothills, Great Central Valley, Central Coast, San Francisco Bay Area and South Coast Ranges. Preferred habitats are wet meadows, edges of vernal pools and ephemeral streams at elevations below 1000 meters.

This wildflower commonly known as Douglas meadowfoam, stands at a height not exceeding 50 centimeters. The name meadowfoam arises from the frothy appearance of an expansive meadow that is dominated with this plant at spring bloom. The leaf has five to 13 leaflets, each leaflet less than three cm in length. The leaflets are often toothed or lobed. Flowers are cup to bell-shaped, with sepals five to 15 millimeters with petals ten to 18 mm; petals ar white, yellow, or yellow with white tips. Petal veins often purple, pink, or cream; stamens are five to eight mm. Fruit is in the form of a nutlets. Smooth obovoid fruits are 2.5 to 5.0 mm in characteristic diameter.

Limnanthes douglasii

provided by wikipedia EN

Limnanthes douglasii is a species of annual flowering plant in the family Limnanthaceae (meadowfoam) commonly known as Douglas' meadowfoam[1] or poached egg plant. It is native to California and Oregon, where it grows in wet, grassy habitat, such as vernal pools and spring meadows. It can grow in poorly drained clay soils. The plant was collected by the Scottish explorer and botanist David Douglas, who worked on the west coast of America in the 1820s.

The plant usually bears white flowers with yellow centers, hence the name "poached egg plant", but flower color can vary across subspecies. It is a popular ornamental plant. It attracts hoverflies and is pollinated by bees. It is self-seeding, even in a lawn.

This plant has gained the Royal Horticultural Society's Award of Garden Merit.[2][3]

There are six subspecies:

  • L. douglasii subsp. douglasii R. Br., is native to the coastal mountains and valleys of southwestern Oregon south to the San Francisco Bay Area
  • L. douglasii subsp. nivea (C.T. Mason) C.T. Mason, with mostly white flowers, grows in the coastal mountains of northern California
  • L. douglasii subsp. ornduffii (E. G. Buxton), with 4 petals instead of 5, is endemic to California's San Mateo County[4]
  • L. douglasii subsp. rosea (Benth.) C.T. Mason, found in California's Central Valley and adjacent hills, often has pink veining on its petals
  • L. douglasii subsp. sulphurea (C.T. Mason) C.T. Mason, is a rare yellow-petaled subspecies endemic to the Bay Area
  • L. douglasii subsp. striata (Jeps.) Morin, has recently been subsumed into this species; it occurs in the Klamath range and the north and central Sierra Nevada
