Been trying to grow this beautiful little plant for many years with mixed results. It's just plain fussy! Needs good drainage. Seems to be quite susceptible to wilting diseases(phytopthera) in my southern Michigan(zone 5) garden.

This survived it's first winter in Zone 3b. It was planted in morning and midday sun and had no sign of damage over the winter. It is still too early to bloom but the plant is putting out quite a number of buds.

This plant is struggling in my garden. I put it in partial shade.

This dwarf rhododendron forms a perfect dome when growing in a fairly sunny location. Perfect rock garden shrub.
