Agapanthus orientalis Black Magic is a darker flowered version of this popular plant that creates a powerful presence in your garden due to its outstanding dark purple flowers that emerge from black-ish buds.
Foliage is as per everday Agapanthus, e.g. straplike, deep green, glossy and densely clumped, making a good border display when not in flower.
These are hardy plants that even fall into the category of 'indestructible' and can look after themselves even if you went on holiday for months.
