The only hardy variety for growing outdoors, Zantedeschia ‘Aethiopica’ is stately and serene. Reaching a statuesque height of up to 90cm, ‘Aethiopica’ stands head and shoulders above most zantedeschia. Pure white, hooded spathes form a sleek vase shape, held above a backdrop of glossy, arrow-head leaves.
Originating from swampy regions of Africa, these perennials prefer a moisture-retentive soil and are well-suited to growing as a marginal water plant.
Bearing the accolade of an RHS Award of Garden Merit for reliability, this robust Zantedeschia ‘Aethiopica’ variety will soon form lush clumps. The sturdy, long-stemmed blooms are highly valued as long-lasting cut flowers.
Plant rhizomes 8-10cm deep in a container filled with good quality, free-draining multi-purpose compost. Provide consistent watering, ensuring the soil stays moderately moist to maintain lush growth of your calla lilies.
Once flowers start to appear, feed plants every 3 weeks with high-potash liquid fertiliser.
Zantedeschia Aethiopica is the only fully hardy member of the family which may be grown outdoors all year round
