Description
This dwarf hybrid certainly has the ‘wow’ factor! Masses of bell-shaped, violet blue flowers smother Rhododendron 'Blue Diamond' in mid-spring. The blooms gradually fade to lavender blue as they age. Dark evergreen leaves cover this bushy little shrub, bringing year round colour to the garden. An ideal choice for bringing a touch of glamour to acid borders, rockeries and patio containers. Height and spread: 90cm (36").

Plant height and spread is seasonal therefore we list by pot size rather than a defined plant size. The height and spread of the plant delivered will vary depending on the season, meaning arrival images are an indication only.

How to Grow
Grow Rhododendrons in moist, well drained, acid soil that has been enriched with plenty of well rotted organic matter. Choose a position in semi or dappled shade with shelter from cold drying winds. Many dwarf Rhododendrons can cope with a sunny position provided that the soil remains reliably moist. Where soil conditions are alkaline, Rhododendron plants are best grown in patio containers, using a mix of ericaceous compost and a soil based compost such as John Innes No. 3. Rhododendrons are surface rooting so it is important to avoid planting them too deeply.
More Info
Water Rhododendron plants regularly throughout the growing season. Where possible, use rainwater as the lime contained in tap water will reduce the acidity in the soil over time. Feed Rhododendrons in spring with a slow release fertiliser for acid-loving plants. Protect plants from cold winter winds. Border grown Rhododendrons will appreciate an autumn mulch to protect their shallow roots from winter cold. Take care not to mound the mulch too close to the stem as this may cause it to rot. If necessary, lightly prune Rhododendron plants in June to remove damaged shoots and restrict size.
