Edith Bosley Rhododendron

Rhododendron x 'Edith Bosley' (H-1)

SKU
06832
One of the best on the market, offering large trusses of blooms for a dramatic spring display. Better than 'Purple Splendor', having larger, deeper purple flowers with a darker flair, along with exceptional cold hardiness and cleaner, longer lasting foliage. Ideal for foundation plantings or mixed borders. Evergreen.
