Clematis cartmanii Sweet Hart

Common Name:
Sweet Hart Clematis

Description:
Clematis × cartmanii 'Sweet Hart' is a compact, evergreen climber originating from New Zealand, renowned for its profusion of waxy white, star-shaped flowers that bloom from late winter through spring. The blooms, approximately 5–7 cm in diameter, are complemented by finely divided, dark green foliage, giving the plant a delicate, fern-like appearance. Unlike many clematis varieties, 'Sweet Hart' does not cling naturally but can be trained over supports or allowed to cascade as ground cover. In Melbourne's climate, it thrives in full sun to part shade, preferring well-drained, humus-rich soils. It's particularly well-suited for containers, hanging baskets, or small garden spaces where its trailing habit can be showcased. Minimal pruning is required, as it flowers on the previous year's growth.
