Beautiful when grown in a container with plants of contrasting colors. It looks great grown with red Bellis and Blue 'Forget-Me-Nots' (Myosotis).

Viola 'Molly Sanderson' is one of the few plants to have black flowers, making it perfect for eye-catching colour schemes. Like most violas, it blooms throughout the summer, benefitting from a quick haircut after its first batch of blooms to encourage more to appear and to keep the plant looking tidy. The fresh young growth that this cutting back produces is also great for using as cuttings material. Not to be confused with Bowles Black (Viola nigra) that can be propagated by seeds. It must be propagated by cuttings as it does not come true from seed. Flowers are edible...looking lovely in a salad..

This black Molly is a perennial, flowering whole season if kept well watered and out of blasting sunlight.
