Timing is key! In the USA, plant seeds indoors 6–8 weeks before the last frost, or sow directly in fall for spring blooms. In warmer regions like the South, fall planting ensures robust growth.
In India, Sweet Williams thrive in cooler Himalayan areas. Sow seeds in early winter for spring flowers, avoiding intense summer heat.

Starting from Sweet William Flower Seeds
