Rhododendron

Mrs. Tom H. Lowinsky Rhododendron

Mrs Tom H. Lowinsky Group (Rhododendron ‘Mrs Tom H. Lowinsky Group’) is an evergreen rhododendron with lavender flowers. Its display arrives late in the rhododendron flowering season, with the exact timing influenced by local weather. Individual flowers measure about 3 inches across. The flower tubes widen into flared faces that display the color clearly. Contrasting orange markings add detail within the flower faces.

The plant develops a rounded outline. 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.
