Rocky Knoll Farm
This dwarf rhododendron species is ideal for bonsai or rock garden growth. Low and compact but boasting a lovely range of purple, blue and pinkish hues. Planting multiples will eventually grow together to form dense ground cover. However, it is suggested to start them planted about 15" apart. The great flowers sit atop attractive silver-grey foliage. It doesn't do as well in heat so we recommend partial shade and watering weekly as needed. Hardy to -15° F.
