Azalea kaempferi 'Johanna'
Masses of large deep red ruffled blooms make a colorful display in mid spring on this hardy, densely branched evergreen shrub. Excellent for brightening a shady location with its long lasting spring color. Dark green small glossy leaves in summer turns to a tinge of burgundy red color in the fall and winter.
Best grown in acidic, humusy, organically rich, medium moisture, moisture-retentive but well-drained soils in part shade. Prefers locations with sun-dappled shade or morning sun with afternoon shade. Avoid hot afternoon sun. Plant in a location sheltered from strong winter winds. Good soil drainage is essential (doesn't like "wet feet"). Poor drainage can cause root rot, therefore raised plantings should be considered in heavy clay soils. Shallow root system (avoid cultivating around shrub) appreciates a good organic mulch (e.g., wood chips, bark, oak leaves or pine needles) to retain moisture and stabilize soil temperatures. Roots must not be allowed to dry out.
