3. Growing On

  • Requires little care once established.

  • Water in very dry conditions.

  • Deadhead to prolong flowering or leave some blooms to self-seed.

4. Flowering

  • Blooms from June to August.

  • Flowers last a few days each, but plants keep producing over weeks.

  • Ideal for wildlife and cut flowers (best picked in bud stage).
