Many Phormium species are now also grown in the Mediterranean as an ornamental plant.
This plant is characterized by special leaves that are available in various colors such as green, yellow, variegata, copper red, apricot, black / violet to red etc.
Flowering time is in July and August and beautiful flowers appear on the long leafless stems.

They become stately and robust plants in a tub that radiate class. A place in the full sun or half shadow is OK, the Phormium is an easy plant.
In the winter it is best to let the tub overwinter at a temperature above freezing and be very careful with watering.
