Limnanthes douglassii is a small annual herb that is native to the west coast of North America. The plants are 1 foot tall and short lived.
Blooming Time: Early Spring The 1 inch flowers are yellow with white tips and fragrant.
Culture: Limnanthes douglassii are easy to culture from seed requiring only moist soil and cool temperatures. In the greenhouse, we use a compost consisting of 2 parts peat moss to 1 part loam to 1 part sand. The plants need full sun and cool temperatures of 50 to 65 degrees. They need to stay moist and do not tolerate drought or high temperatures. Fertilize once during the growing season with a balanced fertilizer. Being annuals they are very short lived. (We will soon lose these as summer approaches!)
Propagation: Limnanthes douglassii are easily propagated by seed with night temperatures of 50 degrees.
Limnanthes douglassii was featured as Plant of the Week June 9-15, 2000.
