Top favorite red flowering rhodo of many collectors I know, this R. arboreum hybrid has many quality traits. For starters, the plant grows strong and full, exhibiting flawless foliage. The flowers are about as red as you can get in stunning ball-shaped trusses. The plant flowers early, mid February into March here in Northern California, when little color is seen, and lights up the view. Originating in England at Caerhays Castle, the plant is a hybrid between R. arboreum and R. thompsonii. It is worth adding to any garden.
