R. arizelum is a fine foliage plant with superb thick cinnamon indumentum on the underside of the leaf! The flowers open pale yellow then fade to pink and finish white! At times it looks like there three different colors on the same plant. This is a distinctive plant of noble bearing. It’s somewhat slow-growing and tends to branch fairly readily. Its bark will develop shades of pink and reddish brown.
If grown in the shade it may grow to six feet in ten years. Sunnier spots will allow for a more compact plant.
This rhododendron will like partial shade. It would love a woodland canopy. Provide
small amounts of fertilizer on Valentine’s Day and Mother’s Day, gentle watering, well-aerated soil with good drainage and avoid a very windy spot.
