Hairy manzanita

Hairy manzanita (Latin: Arctostaphylos hispidula) is an evergreen shrub belonging to the Ericaceae family. It is a distinctive member of the genus, characterized by the glandular hairs present on its new growth, which distinguish it from other manzanita species. This plant is primarily cultivated for its architectural form and year-round ornamental foliage.

Originating from the coastal ranges of Oregon and Northern California, this species is adapted to Mediterranean-like climates with dry, hot summers and cool, moist winters. It is typically found in chaparral or coniferous forest understories, occupying well-drained, nutrient-poor slopes where other plants might struggle to establish.

The botanical structure of Arctostaphylos hispidula is highly specialized for moisture conservation. It features thick, leathery leaves with a waxy cuticle and deep root systems that allow it to access water deep within the soil profile. The plant typically reaches a height of one to three meters, forming a dense, rounded shrub that can serve as a focal point in xeriscaping.

Agricultural success with this plant depends entirely on soil management. It is strictly calcifuge, requiring acidic soils, and absolutely demands impeccable drainage. Incorporating coarse inorganic materials like pumice or gravel into the planting medium is essential. Over-fertilization should be avoided, as the species is adapted to infertile soils and may suffer from root burn or excessive, weak growth if provided with too much nitrogen.

• Thrives in full sun to partial shade
• Requires acidic soil with excellent drainage
• Extremely drought tolerant once established
• Provides habitat for native pollinators and birds

In landscaping, it is used for erosion control on slopes and in low-water gardens. Pests such as aphids and spider mites may occasionally infest the foliage, but the primary threat remains soil-borne pathogens like Phytophthora, which thrive in stagnant, wet conditions. Maintaining a mulch-free zone directly around the trunk is recommended to improve air circulation and prevent bark decay.
