Sticky manzanita

Sticky manzanita (Arctostaphylos viscida) is an evergreen shrub or small tree belonging to the Ericaceae family. The plant is widely recognized for its glandular, sticky foliage and smooth, reddish bark that exfoliates with age. It is a resilient species that thrives in challenging environmental conditions, particularly in western North American shrublands.

The native range of this species covers parts of California and Oregon, where it frequently grows in dry mountain slopes and woodlands. It is well-adapted to the Mediterranean climate of the region, characterized by long, hot, dry summers and cool, wet winters. Given these traits, it has become an increasingly popular choice for water-wise gardening.

Botanically, Arctostaphylos viscida is defined by its tough, leathery leaves and distinctive urn-shaped flowers that appear in early spring. The plant produces small, berry-like fruits that serve as a crucial food source for diverse wildlife, including birds and small mammals. Its growth habit can be quite variable, ranging from a low-spreading shrub to a small tree depending on the local site conditions.

Regarding cultivation requirements, the species demands full sun exposure and excellent drainage to prevent root rot, which is its most significant vulnerability in garden settings. It performs exceptionally well in poor, rocky soils and does not require fertilization once established. Growers should emphasize the importance of deep, infrequent watering during the first year of planting, followed by minimal maintenance.

• Extremely drought tolerant once established.
• Needs well-drained, acidic to neutral soil.
• Provides essential habitat for local wildlife.
• Requires minimal pruning and fertilization.

The primary horticultural use of sticky manzanita is in xeriscaping and ecological restoration projects. It is highly valued for its ability to stabilize loose, rocky slopes and its inherent resistance to drought. While not a conventional agricultural crop, it is an essential plant for managing landscapes that prioritize resource conservation and ecological health.
