Currently "on fire" in the shady front corner of the yard under the black walnut tree, today's favorite plant is Rhododendron x azalea Gable Hybrid 'Stewartsonian'. A semi-dwarf azalea with vivid, brick-red 2" single blooms.
It's very hard to ignore its densely packed, fire engine red, mass of flowers. The flowers are so dense that I can barely see the leaves.
This shrub can be 5-6' tall by 4' wide. Generally, they seem to be more upright, but mine has been sprawling, with occasional entire branch pruning by my rambunctious Assistant Yvette.
Out of bloom, the leaves are 1" long, dark green and glossy.
Best grown in organic-rich, moist and well-drained soil in a part sun to part shade exposure.
Hardy to -20 degrees, so perfect for Portland.
