Before planting
- Allow enough room at the front of a border or beside a path because the stems spread widely as the season develops.
- Choose soil that drains well but does not dry out completely while the plant establishes.
Why choose it
- Flowers for months, often from early summer until autumn.
- Softens border edges and fills spaces between shrubs or taller perennials.
Care
- Water during prolonged dry spells, especially in the first growing season.
- Cut back untidy growth after the first main flush if you want a fresher, more compact mound.
- Divide an overcrowded clump in spring when growth begins.
Good to know
- The registered cultivar name is 'Gerwat'; 'Rozanne' is the familiar trade designation, and 'Jolly Bee' is an older synonym.
