What Is the Ideal Temperature Range for butterfly bush?
Butterfly bush shows remarkable resilience to temperature fluctuations, enduring cold as low as -10℃ (14℉) and heat up to 41℃ (106℉). This broad tolerance implies that while butterfly bush can thrive in diverse climates, it might need protection during severe cold or heat waves. Symptoms of stress from low temperatures include frost damage and dieback, while excessive heat might cause wilting and leaf scorch. In cold conditions, mulching and covering the plant can help, whereas during extreme heat, adequate watering and partial shading are essential. Thus, butterfly bush's temperature tolerance significantly impacts its care regimen, ensuring it remains healthy across varying environments.
