About this species
Rhododendron hybridum plants reach, depending on the variety, 1.5 to 3 metres in height and spread, with a dense, rounded habit. The flowers, gathered in terminal umbels, appear at the tip of each branch and last two to three weeks.
They need acidic soil, rich in organic matter, moist but well drained, and do not tolerate lime or waterlogging. They prefer partial shade and shelter from wind and summer sun, especially in the South.
The roots are shallow, so they benefit from a mulch and from regular watering in summer. Removing the faded flowers favours the next flowering.
