Flowers from the second year from June to August. It is drought-resistant, its water needs are limited and requires little maintenance: cut dried stems once a year. Sowing the large-headed knapweed Sow under cover in March-April at 20°C, keep moist. Transplant into a pot at the 3cm seedling stage, grow in a pot at 15/18°C and plant 80cm apart.
