Its elegant spires of violet-blue, trumpet-shaped blooms create a stunning contrast against deep green foliage, adding soft colour to garden beds for months on end. Highly resilient, it handles heat, dry spells, and light frosts, making it a top choice for Australian gardens. Loved by bees and beneficial insects, this easy-care perennial is perfect for borders, mixed plantings, or as a cut flower.
