Long-lasting whisky-coloured flowers with distinctive dark red spotting. RHS Award of Garden Merit winner. Flowers in May. Height 140-160cm. Supplied in a 5 litre pot. Inkarho Rhododendrons are lime-tolerant plants that will flourish in your garden! You may well have tried to grow rhododendrons & found that they have not flourished. Often this has been because of their specific requirements for a p H of 4 to 5.5 (which most garden soils do not fall into) to maintain strong, healthy growth. Inkharo rhododendrons are different! 25 years of breeding work across 15 different nurseries, testing over a million seedlings, has resulted in an Inkarho rootstock whose stronger root systems are more resistant to salt, & will tolerate sandy soils & clay soils with a higher p H! All the wonderful, well-known varieties have then been skillfully grafted onto this lime-tolerant rootstock, allowing you to successfully grow these magnificent plants in your own garden soil! Hardy to -24C.
