Growing notes
- Native to the Atlantic Forest of southeastern Brazil
- Distinct flower colour-change through 3 days is the defining ornamental feature
- Demands acidic soil and humid conditions — chlorotic on alkaline soils
- 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.
