Black Calla Lily - Bulb

Zantedeschia 'Schwarzwalder'   

Almost Black Calla Lily

Impressive calla lily (Zantedeschia 'Schwarzwalder') with narrow, vase-shaped flowers that are almost black in colour. With a height of 50-60 cm, this variety is ideal for a medium-sized container. The fresh green leaves provide added appeal. Zantedeschia develop their leaves first, followed by the eye-catching flowers. They can be planted out in the garden after mid-May, but do not forget to take them indoors before the first night frost strikes.

Plant your Calla Lilies 'Schwarzwalder' in humus rich, well-drained soil in an area with complete sunshine. You can improve poor soil by mixing in some compost. The roots should be set at about 10 cm deep. Zantedeschia thrives in a rather moist soil. Always use fresh potting compost if planting in pots or window-boxes.

Combining Calla Lily with other plants

‘Schwarzwalder’ will feel at home planted in a corner of your garden in moist soil alongside hostas. Especially one with blue-green leaves which will contrast nicely with the burgundy tinted bracts of the Calla Lily. You can also plant several different coloured Calla Lilies together in a large planter.

Did you know that the Calla Lily 'Schwarzwalder' is grown for its showy spathes? The vase-shaped burgundy coloured 'flower' is not actually a flower at all. The real flowers are tiny and grow on the little, pale yellow spadix, which is almost completely surrounded by the leaf-like graceful spathe. As its wonderful spathes last so long, Calla Lilies are very popular as cut flowers. The Calla Lily is also called Zantedeschia.

Zantedeschia as a cut flower

Want to cut some Calla Lilies for the vase? Pluck the complete stem carefully from the plant. The arrow-shaped, often spotted, leaf looks great in bouquets too.

Give (Zantedeschia) ‘Schwarzwalder' lots of water in the summer – the soil should remain slightly damp. For more profuse flowering, we recommend regularly adding plant food to the watering can when watering. During dry periods, for plants in pots, keep a saucer with water in under the pot. When the plant is no longer flowering, you can stop feeding.

Calla Lilies need protection through the winter

The Calla Lily is not a hardy plant, so does not tolerate frost. Therefore it is advisable to grow them in pots that can be brought in for the winter. Keep the potting soil on the dry side during this time but do not allow it to dry out completely. A little more water can be given early spring and the Zantedeschia 'Schwarzwalder' can go outside shortly after. Bring indoors again if frost is forecast.
