Title: Response of Penstemon Fruticosus to fertilization

Author: Klock, G. O.;

Date: 1976


Publication Series: Research Note (RN)

Description: Bush penstemon (Penstemon fruticosus (Pursh) Greene), an attractive ground cover on east Cascade slopes, appears to survive under low fertility, xeric conditions. These plant characteristics are desirable for revegetating severely disturbed areas. Seedling response to fertilization was tested to find if growth rates could be increased to provide quicker ground cover with new plantings. Bush penstemon does respond to nitrogen and phosphorus fertilization under greenhouse conditions. It appears that, with adequate soil moisture, 50- to 100-ppm nitrogen is sufficient for nearly maximum growth response

Keywords: Nitrogen fertilizer response, inorganic fertilizer, nursery beds, growth regulators, erosion, vegetation
