Horticultural selection from Arctostaphylos edmundsii. Arctstaphylos edmunsii 'Bert Johnson' originates from the Tilden Botanic Garden, and is a special selection from A. edmunsii manzanitas growing in the county of Monterey, California. A. Bert Johnson is a low growing manzanita that forms a nearly perfect mat, standing less than 1 foot high but spreading 6 feet. This manzanita makes an excellent ground cover and is equally attractive spilling over walls or boulders. Bert Johnson's cascading habit allows it to thrive on hillsides; its low branches root as they spread, helping to keep the soil in place and erosion under control. Bert Johnson manzanita is also known by the name Bronze Mat manzanita, owing to the fact that the new growth on this plant is tinged a delicate bronze color. The densely clustered leaves are small on this manzanita, and a dark gray-green color, giving the plant a sophisticated appearance reminiscent of boxwood. In late winter and spring, A. Bert Johnson is covered in pink-tinged white flowers, and is beloved by butterflies and hummingbirds. A. Bert Johnson would like full sun in coastal conditions, but might benefit from a little afternoon shade in very hot inland areas. This plant prefers well-drained soil, enjoying occasional summer watering to look its best but ultimately remaining staunchly drought tolerant. A great choice for a native groundcover. Tolerates almost any soil type. Prefers sun in coastal sites, and part shade in inland sites. Introduced by Tilden Botanic Garden.
