"I love their famous Trebah Flans, yummy!" P. Atkinson, Truro

Rhododendron Valley

TrebahÙs rhododendrons take centre stage in spring. By late March and into April, the whole valley is full of rhododendron flower; Trebah has literally hundreds of specimens, ranging from the ‘home grownÙ Trebah Gem with its soft pink blooms, to the mighty Himalayan tree rhododendrons, such as R .arboreum. The magnificent ‘Glory of PenjerrickÙ, a rhododendron with possibly the deepest pink flower of all to the delicate Indian R. nuttallii with its fragrant, pale yellow, lily-like flowers. You can well understand why a hundred years ago, villagers from Mawnan Smith used to describe a walk through Trebah as ‘coming up paradiseÙ.

Rhododendron 'Trebah Gem' was originally planted at Trebah by Head Gardener Harry Thomas in 1900.
