White Lights Rhododendron is an extremely floriferous member of the Northern Lights Azaleas.
|full sun to partial sun
|tolerates average moisture conditions, during dry spells extra water is beneficial
|Soil & Site
|Prefers acid, organic rich soil moist soils. I give my plants a helping of soil sulfur twice a year to help keep the acidity level within the proper range. Mulching with pine needles helps to maintain soil acidity
|proven hardy to -35 degrees F
|flower buds white with a pale pink cast, white flowers with a slight yellow blotch
|5 by 5 feet, plants are rather twiggy
|I like to dig a large hole, not to deep and mix the soil with 50% peat moss or compost. Plant in a slight mound for good drainage. Add a cup or two of Ammonia sulfate (or an other acid producing fertilizer)add some regular fertilizer. Water in good and keep moist. Mulch will help to slow down the loss of water. I like to add acid fertilizer in the fall and spring. Also you can use a liquid acid fertilizer such as Mir-acid.
|Introduced by the University of Minnesota USA. It is a hybrid between Rhododendron prinophyllum and a white flowered Exbury hybrid.
