The Calla is originally a South African swamp plant and comes from the Arumeake family (Araceae) . This family consists of monocotyledonous plants. The flowers are collected on a fleshy ear 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 copies to Europe, where it has grown into a beloved room and terrace 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 species 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 works best in a light location with a moist, well-drained soil. That means a strong splash of water two or four times a week as long as the plant blooms. No water may remain in the pot.
