Growing notes
- Plant in sheltered sunny positions in mild-climate gardens — flowers continuously over a very long late-season window when little else of this brilliance is in bloom
- Frost-tender — succeeds outdoors in zone 9 and warmer, treated as a container plant elsewhere
- Cut back hard in spring to encourage compact bushy growth and abundant flowering
- Listed as a mild invasive in parts of Hawaii — check local guidance before planting
- Not reliably hardy outdoors in Canada — Canadian zone values shown represent the system maximum and do not imply garden cultivation north of the warmest coastal pockets.
