Description
Louis Edmunds manzanita grows into a tall evergreen shrub with an upright branching habit, 8-10 ft. tall and 6-8 ft. wide. Foliage is comprised of 1" large pale green leaves; late winter flowers are light pink and attract hummingbirds. It's distinctive bark is very dark purple.The Louis Edmunds manzanita is a popular landscape cultivar selected from a stand of Arctostaphylos bakeri growing in Sonoma County. The combination of dark bark color and light foliage make it a highly attractive shrub for background and specimen uses, particularly when pruned to reveal its structure. When grown in the Inland Empire, it needs protection from hot afternoon sun and careful summer watering. It grows well with toyon, sugar bush, buckwheats, coast live oak and other California natives.
Water Needs
The Louis Edmunds manzanita is well adapted to normal winter rains and periodic summer irrigation. Established plants grow well with periodic deep irrigation in the summer. Manzanitas are vulnerable to disease problems when summer irrigation produces moist soil and leaf litter conditions that enable active fungi and bacteria growth.The chart shown below provides a recommended baseline guide to the monthly irrigation schedule and volume of supplemental water needed to maintain healthy growth throughout the average year. It should be noted there are several months marked by an asterisk (*) when winter rains can provide sufficient moisture and irrigation is not needed. The high and low range of moisture indicates it can grow with varying amounts of water; it is desirable to have leaf litter and the top layer of soil beneath the stems to dry out between irrigation applications.

Maintenance
In general Manzanitas do not need much pruning. Carefully select the right species or cultivar for a fully mature size that fits your space well. Carefully thin or "skirt up" manzanitas to expose beautiful branches in November, after risk of sunburn from long summer days has passed (1). Manzanitas occasionally get bright red growths on the edges of leaves. This is manzanita leaf gall aphid, a small insect that causes the plant to create this reaction. It is generally not threatening in healthy plants, but can spread. Growth affected by leaf gall aphid may be pruned out after winter-spring flowering (4).References
