This white flowering Azalea is a delightful addition to the shrub border, and adds a delicate and refined character to the garden. They are named Sweet Azalea after their sweet-scented aroma. Rhododendron arborescens is one of the hardiest azaleas and one of the last azaleas to bloom in the spring. Plant them in shady areas in your garden in acid soil.

Harvesting

Harvest seeds after flowering.

Propagation

Cuttings

Softwood cuttings are taken from the new growth. The cutting environment should be humid because any wilting will stress the cuttings.

Seed

Remove and clean the seeds before storing. Do not cover the seeds with a medium like perlite, just sprinkle the seeds on top of a sandy soil mixture.

Layering

Place a branch on the soil and place a rock to keep some of the eyes in contact with ground and excluding light. After 1-3 months roots will grow from the covered eyes!
