Botanical illustration's enjoying a renaissance at the moment, including here in New Zealand which is taking part in an international botanical art exhibition. Each country's working on a show highlighting indigenous plants. We have a wealth to choose from, and a group of enthusiastic illustrators working on submissions for the exhibition. The American Society of Botanical Artists came up with the idea and the event will mark the first Botanical Art Day on May 18th, 2018. Lynn Freeman gathers together three artists with very different styles, but with a shared love of flora - Lesley Alexander, Sue Wickison and Sandra Morris.
