Peak Bloom & Maintenance
6-12 weeks or until frostPlant is in full, dense flower with maximum color display; maintains compact mounded shape; very ornamental
Continue regular watering and fertilizing; pinch back any leggy growth; remove yellowing leaves; provide afternoon shade in extremely hot climates (above 90°F) to prevent flower fade

Fun Facts
- 🌱 The name 'Impatiens' comes from the Latin word 'impatiens,' referring to the plant's seed pods that explosively burst and scatter seeds when ripe—a mechanism called ballistic seed dispersal.
- 🌱 Telstar Mix flowers in multiple colors from a single seed packet due to hybrid genetics, making each plant potentially different and creating a vibrant, multicolored display.
- 🌱 Impatiens are native to tropical rainforests and mountainous regions of Africa and Asia, which explains why they thrive in shade and humid conditions—they're adapted to the forest understory environment.
