Rhododendron Dora Amateis

Dora Amateis Rhododendron

Dora Amateis (Rhododendron ‘Dora Amateis’) is an evergreen rhododendron with white flowers. Its display arrives in the early-to-middle part of the rhododendron flowering season, with the exact timing influenced by local weather. Individual flowers measure about 1¾ inches across. The flower tubes widen into flared faces that display the color clearly. The flowers have a degree of fragrance. Clusters commonly carry about 6-8 blossoms. Contrasting yellow markings add detail within the flower faces.

Its foliage is retained through winter, keeping a leafy framework between flowering seasons. It can provide a flowering focal point within a mixed shrub border or woodland-edge planting.

Give it acidic, humus-rich soil that stays moist and drains freely. A sheltered position with filtered light or morning sun is a useful starting point; protect the roots from prolonged drying and keep mulch clear of the stems.
