Trewithen's Head Gardener Gary Long is keen to point out the highlights.
He said, "The Asiatic Magnolia are covered in warped twisted fruit. The Viburnum betulifolium are displaying translucent bunches of red berries, which will continue until March next year. We have had a good stand of this plant since pre 1937 when the Royal Horticultural Society wrote about the plants in their journal.
The Hydrangea are a riot of colour with not just the usual blues, but the Hydrangea paniculata are really stunning with large creamy white and pink panicle flowers.
"Out of season" Rhododenron and Magnolia, some trees and shrubs turning to their autumn colour, the huge Schima with camellia flowers on a tree the size of a mature oak and a second flush of roses in the Rose Garden add to an amazing riot of colour for this time of year."
Once the gardens have closed at the end of September, the Plant Centre and Tea Shop will remain open until 31 October. The Plant Centre stocks a wide variety of ornamental trees, shrubs and herbaceous perennials, grasses, ferns and exotics with many propagated from Trewithen's own plants, trees and shrubs. Cornish spring bulbs and Cornish grown roses are in stock. Special offers on selected plants.
Located close to the Plant Centre, Trewithen's Tea Shop offers tasty homemade food using local ingredients.
