Rhododendron 'Blue Silver' has rigid evergreen foliage with an interesting silvery lustre that reflects light brilliantly. From late March onwards, this compact, bushy dwarf hybrid offers a show of mauve-colored blooms. This variety grows especially well in small pots and rockeries, making it ideal for patio pots and rockeries, as well as groupings at the front of acid borders. Height and spread: 75cm (30).
