Zantedeschia ( Calla )
Number of flowers: 5+
The Calla is originally a South African marsh plant and comes from the Arum family (Araceae). This family consists of monocot plants. The flowers are collected on a fleshy spike, surrounded by a bract. This bract is often attractively colored.
The Calla was discovered in 1725 by the then European governor. He sent a number of specimens to Europe, where it has become a popular indoor and patio plant.
The tubers of the Callas come from California. These tubers are two years old and are potted in the nursery. The cultivation time depends on the variety and the period in which it is planted and varies between 10 and 16 weeks. The Calla is available during the period from February to December.
The Calla is an easy plant that has no special requirements. The Calla grows best at a temperature between 10 and 20 degrees Celsius. The flowers stay fresh longer in a room that is not too warm. The Calla also tolerates lower temperatures, but will then no longer grow.
It does best in a light position with moist, well-drained soil. That means a good splash of water two to four times a week as long as the plant is flowering. No water should remain in the pot.
