RHODODENDRON ENGLISH ROSEUM
English Roseum Rhododendron has non fragrant lilac-pink flowers with orange blotches. A late mid-season grower that reaches 6 feet in 10 years and is hardy to zone 4 (-25 degrees F) English Roseum Rhododendron is more tolerant of sun, humidity and cold than some other rhododendron varieties.
Rhododendrons and azaleas grow best in light, well-drained soils with good soil aeration and an ample supply of soil moisture during the summer. Rhododendrons and azaleas, in general, require an acid soil with pH about 5.5. Soils with pH higher than 5.5 should be acidified. Rhododendrons and azaleas are easily damaged or killed by planting too deeply. Partial shade is desirable in most cases; in hot dry areas it is essential. Most varieties simply will not tolerate full sun, developing quite yellowish leaves under such conditions you will do well to plant rhododendrons in locations where the plants will receive shade in the afternoon.
