  • Photo of Rhododendron minus (Rhododendron minuss)

Phonetic Spelling:rho-doh-DEN-dron MY-nus

Genus:Rhododendron

Species:minus

Family:Ericaceae

This plant is a woody shrub, either evergreen or deciduous, belonging to the Ericaceae family. It typically grows in an upright, rounded, and dense manner, with its shape becoming more irregular as it matures. The leaves are elliptical, featuring a dark green, leathery texture, and when crushed, they emit a pleasant aromatic scent. This shrub is particularly suitable for mass planting.

It thrives best in partial shade and prefers cool, moist, well-drained, acidic, and nutrient-rich soil. While it can withstand full sun in certain locations, it is advisable to avoid areas that are windy.

Wildlife Benefits: The flowers of this shrub attract hummingbirds, and the genus Rhododendron is known to support the specialized bee species Andrena (Andrena) cornelli.

Insects, Diseases, and Other Issues: Rhododendrons are prone to various insect infestations and diseases. Common insect pests include aphids, borers, lacebugs, leafhoppers, mealybugs, mites, nematodes, scale, thrips, and whiteflies. Leaf spot disease may occur if the plant is grown in deep shade or experiences drought stress. Other potential diseases include canker, crown rot, root rot, rust, and powdery mildew. Exposure to full sun can lead to leaf scorch, and poor drainage can cause root rot. However, with proper care and placement, a healthy plant should encounter minimal issues.
