Rhododendron ‘Cosmopolitan’ is a captivating evergreen shrub known for its stunning display of large, vibrant flowers. This variety features clusters of bright pink blooms with a touch of lavender, creating a striking contrast against its glossy, dark green foliage. ‘Cosmopolitan’ is perfect for adding a splash of color to garden beds, borders, or shaded woodland areas, making it a versatile choice for enhancing your garden’s aesthetic.

For optimal growth, plant Rhododendron ‘Cosmopolitan’ in a location with partial to full shade and well-drained, acidic soil. This shrub thrives in environments where it receives morning sun and afternoon shade or in dappled light, which helps protect the foliage and maintain the vibrancy of the blooms. It is well-suited for cooler climates and can enhance shaded or woodland gardens with its striking flowers.

‘Cosmopolitan’ typically blooms in mid to late spring, offering a beautiful floral display. To support healthy growth and maintain abundant blooms, feed the plant with a balanced, acid-loving fertilizer formulated for rhododendrons and azaleas in early spring, as new growth begins.

Pruning should be done immediately after flowering. Remove spent blooms and any dead or damaged branches to preserve the shrub’s shape and promote vigorous growth. Avoid heavy pruning, as ‘Cosmopolitan’ naturally maintains a compact form.

Rhododendron ‘Cosmopolitan’ is an excellent choice for adding vibrant color and elegance to your garden, with minimal maintenance required to keep it thriving.
