Flowers and Fruits

Distribution

Cultivation

The grasses prefer a sunny situation. The substrate should be loamy, sandy-loamy, clay, sandy clay or loamy clay and comparatively poor with a pH between 4 and 7,5. The plants need a soil depth of at least 30 centimetres for good growth. They tolerate temperatures down to -29°C (USDA zone 5) and need a frost-free period of at least 14 weeks.
