Calla Lily 'Rehmannii' - Tuber
Calla Lilies 'Zantedeschsia rehmannii' can easily be grown indoors. Plant the tuber in a pot of good potting compost. Immediately place in full daylight in the house, and water regularly. The leaf develops first, after which the eye-catching flower appears. Callas 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 ‘Zantedeschsia rehmannii’ 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. Zantedeschsia rehmannii thrives in a rather moist soil. Always use fresh potting compost if planting in pots or window-boxes.
Combining Calla Lily with other plantsIf you have a rather boggy corner in the garden, the Zantedeschia ‘Rehmannii’ is lovely combined with the Hosta. Especially one with blue-green leaves which will contrast beautifully with the pink coloured flowers of the ‘Zantedeschsia rehmannii’. Calla Lilies in different colours planted together also look great in a large planter.
Did you know that the Calla Lily 'Zantedeschsia rehmannii' is grown for its showy spathes? The vase-shaped pink 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.
Zantedeschsia rehmannii as cut flowerWant 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) ‘Rehmannii’ 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. Stop feeding when there are no more flowers.
Calla Lilies need protection through the winterThe 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 ‘Rehmannii’ can go outside shortly after. Bring indoors again if frost is forecast.
