Rosewells, designed by the garden owners, has developed over the last 25 years with an underlying theme that each part of the garden should work in relation to the rest to create one overall effect. The design centres on texture and foliage to provide a lively effect with structure and shape all year. The winter ‘bones’ are provided with trees and shrubs with features such as contorted stems and peeling or coloured bark. In spring and summer, texture and coloured foliage of shrubs and perennials add to the overall design. Birgitta sees flowers as an added bonus with scent and colour being important and combinations of yellow, blue and white colour schemes are preferred. The garden has many varieties of cornus, magnolias, trilliums, meconopsis, agapanthus, rhododendrons, primulas, auriculas, fritillaries, erythroniums, peonies and acers, which are favourites.
