These are just two Rhododendrons which stand out at present. Rhododendron augustinii is a beautiful chinese species discovered in china by Augustine Henry in 1899. High Beeches has a particularly good blue form.
To contrast a Rhododendron cinnabarinum
hybrid. Rhododendron cinnabarinum was introduced from the Himalayas by Sir Joseph Hooker in 1849, sadly it is prone to powdery mildew but this unnamed hybrid is slightly more resistant than the species.
