Rhododendron yak. 'Ken Janek' (aka Rhododendron yakushimanum 'Ken Janek') is a compact, mounded evergreen rhododendron prized for spring trusses of deep pink buds that open to soft pink flowers and often fade lighter toward white. You get year-round structure from its dense habit and glossy, leathery foliage, plus a big flush of color when it blooms.

Plant it where your site provides partial shade or dappled light, especially protection from hot afternoon sun. In cooler climates it can take more sun, but consistent soil moisture is key. Provide acidic, humus-rich, well-drained soil, and mulch to keep roots cool and evenly moist while avoiding waterlogged conditions.

At maturity, expect roughly 24-36 inches tall with a broader spread, making it a strong choice for foundation plantings, woodland edges, and mixed shrub borders. Give it room for air flow and pair it with acid-loving companions such as azaleas, pieris, and ferns for a layered look.

Prune only if needed, right after flowering, and deadhead spent trusses to keep the plant tidy and direct energy to growth. Protect from drying winter winds, water during dry spells, and keep the root zone mulched to help the plant settle in and perform at its best year after year.
