Petunias are annual flowering plants that thrive in full sun (6+ hours daily) with well-draining soil. They're known for their prolific blooming from spring through fall, attracting pollinators like butterflies and hummingbirds to your garden. Water regularly, allowing soil to dry slightly between waterings, and fertilize monthly for optimal growth.

These seeds are suitable for USDA zones 2-11 as annuals (grown in all zones during frost-free periods). Start seeds indoors 8-10 weeks before last frost, or sow directly after danger of frost has passed. Seeds require light to germinate - press gently into soil surface without covering. Germination typically occurs in 7-14 days at 70-80°F. Plants reach 10-15 inches tall with a spreading habit ideal for ground cover or cascading from containers.

Each order includes 500 Petunia Grandiflora seeds with high germination rates. Create a spectacular color show in your garden with these easy-to-grow, heat-tolerant flowers that provide continuous blooms throughout the growing season.
