Plant calla lily tubers in pots during March or April and grow them somewhere bright and frost-free. Alternatively, plant directly outside in May, once the risk of frost has passed.

Calla 'Schwarzwalder' (black forest) is one of the most intriguing flowers in terms of its colouring. Is it red with a black interior or totally black, edged with red? Or black edged with deep maroon? Not that it matters, really, which of these colour choices your individual plants make, a few Calla 'Schwarzwalder' plants will certainly give your garden a spectacular boost in terms of dramatic content and elegance. All will also surprise you with the optical illusion the velvety sheen of the flower of Calla 'Schwarzwalder' creates: That the dark hollow of the funnel seems filled with liquid almost ready to drip out of the bloom’s pointy spout.
Gracy's gardening tip
"Some Calla varieties (like 'Schwarzwalder') come with an attractive white dotted foliage, giving them even more flair!"

Plant profile
Plant calendar
Grow calla lilies in full sun or partial shade, sheltered from strong winds. They thrive in borders and containers filled with rich, free-draining soil or compost.
Space the tubers around 20–30cm apart. For containers, use fresh peat-free multipurpose compost and choose a sturdy pot with good drainage.
Position each tuber with its buds or ‘eyes’ facing upwards. Cover it with around 1cm of soil, or plant it on its side if you are unsure which way is up.
Water lightly after planting and avoid saturating the compost while the tubers remain dormant. Once shoots appear, water regularly and do not allow the soil to dry out.
Allow the foliage to yellow and die back naturally in autumn. Lift tender calla tubers and store them somewhere dry and frost-free, or move container-grown plants under cover for winter.
