Christiana studied Graphic Design and Natural History Illustration at Bournemouth and Poole College of Art and Design. She was educated at Sidcot School in Somerset during the 1970s where she first studied art. In the 1990s she was commissioned by Major William Spowers to paint trees and shrubs for Windlesham Arboretum in Surrey, and has produced work for the Wildlife Trusts as well as private clients in the UK and abroad. Her painting ‘Winter Oak Leaves’ is held in the RHS Lindley Library art collections.
With a love of trees, her emphasis is on leaves found in autumn and winter, the structure of cones, seeds and fruits and the life cycle of plants. She paints in watercolour, working directly from life to focus on observational drawing and detail. Christiana also paints shells, fossils and seaweeds found along the tideline.
