Honestly, we are nuts about kalmias – mountain laurels. Not very well known, these mid-sized shrubs deserve more attention as they belong to the most beautiful flowering evergreen shrubs of our climate. They come from south-eastern USA and the Asian mountains where they grow under taller trees.

Raspberry Glow has deep red buds and dark rosy pink flowers. This variety is renowned for its attractive, healthy foliage. Leathery leaves are narrow, laurel-like, pointed, mid green and partly glossy.

There are many cultivars combining all sorts of red, pink and burgundy shades with white, all of them beautiful, all of them very hardy. The best display is when half of the bloom cluster is still in buds which mostly have a different colour than the flowers themselves.

For a happy life it MUST HAVE acidic soil (add plenty of peat). Plant it in well drained soil that has to be well mulched to keep the surface roots moist at all times. Full sun is best for best colouring. Fertilize in spring and autumn with rhododendron fertilizers. Use water solutions or slow-release fertilizers that will not burn the delicate surface roots. Fully hardy to -34°C (USDA zone 4).
