Leptospermum scoparium ‘Wiri Donna’ bears large, single, crimson flowers in the spring, which create a striking visual contrast against the beautiful, purple-red foliage. Leptospermum scoparium ‘Wiri Donna’ is hardy and prefers full sun with free-draining soil, and is also frost and drought tolerant once established, making it a great choice for a variety of growing conditions. Leptospermum scoparium is evergreen and native to New Zealand and the states of New South Wales, Tasmania, and Victoria in Australia. Learn more about Leptospermum scoparium. Leptospermum scoparium ‘Wiri Donna’ was developed by Jack Hobbs of the Auckland Regional Botanic Gardens in New Zealand in the late 20th century.
