Sunflowers typically take about 70 to 100 days to reach maturity, depending on the variety and environmental conditions. In cold temperatures, growth may be slower due to reduced sunlight and lower temperatures, which can delay germination and overall development. It's essential to ensure that sunflowers are planted after the last frost and in soil temperatures above 50°F (10°C) for optimal growth. If exposed to prolonged cold, their growth may be stunted or they may fail to thrive.
