The Zantedeschia Calla is originally a South African swamp plant and comes from the Arumeae family. This family consists of monocotyledonous plants. The flowers are collected on a fleshy spike, surrounded by a spathe. This spathe is often attractively colored.
In 1725, the Calla was discovered by the then European governor. He sent a number of copies to Europe, where it has become a popular room and terrace plant.
Calla is a swamp plant that firmly anchors in banks. The plant grows from South Africa to Malawi, often in places where rainwater runoff is obstructed. This creates a brief swamp-like situation in which Calla stores moisture in its bulbs. And they help him through the dry periods.
The tubers of the Callas come from California. These tubers are two years old and are potted in the nursery. The cultivation period depends on the type and the period in which the planting takes place 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. In a not too warm room, the flowers stay fresh longer. The Calla also tolerates lower temperatures, but will no longer grow.
It is best suited to a light position with moist, well-drained soil. That means a firm splash of water two or four times a week as long as the plant blooms. No water should remain in the pot.
Zantedeschia Calla is an easy plant and gives flowering pleasure for weeks.
