Wilna grew up on a farm in the Limpopo Savannah. Her father encouraged her to understand the botany of the veld and indigenous flora. In 1998 she decided to practice botanical art as a keen hobby, which developed into a full- time pursuit. She attended botanical Art workshops with James Le Roux and master classes with Jenny Phillips. Her medium is water colour with specialization in indigenous trees and plants.
Her works received various degrees of recognition at the bi-annual Kirstenbosch Biennale:
2006 and 2008- Gold
Wilna comments” My desire to focus on a specific aspect of my subject is a microcosm expression representing a layer of the whole. My paintings are extremely intimate.
