Beautiful, but poisonous - that could be the motto of the room calla. The exotic-looking calla now presents its chalice-shaped flowers in different colors and, as a houseplant, is a noble eye-catcher. However, it is a plant with a claim. However, those who know how to deal with it will enjoy the Zantedeschia. The plant, which comes from southern Africa, lives on the edge of swamps that regularly dry out. That's why she needs a dry winter break with us too. But then it comes back with all its glory.
