(Helianthus annuus)
EXCLUSIVE – These grand giants are fun and easy to grow with dramatic results. Kids of all ages will love them! The big-framed, strong plants reach from 12 to 16 feet tall to follow the sun; their brilliant golden flower faces make the entire garden a glorious bright summer celebration. A row of Sunzilla makes a wonderful living hedge that grows before your eyes. After flower petals drop and seeds have matured, the big heads of plump kernels make a feast for neighborhood songbirds.

EASIEST TO START DIRECTLY IN THE GARDEN

Plant in full sun in good garden soil when weather is warm and settled both day and night and all danger of frost is past. Poke seeds into well-worked soil about 1 inch deep, 6 inches apart. Press soil firmly over seeds and keep moist as seedlings emerge.


TO START EARLY INDOORS

Several weeks before last frost date, sow seeds 1 inch deep in individual pots of well drained seed starting mix. Keep moist and provide a strong light source until seedlings are ready to plant outside. Transplant carefully, disturbing the roots as little as possible.


THIN OR TRANSPLANT

When seedlings are about 3 inches tall, space them 12 – 18 inches apart with 3 feet between rows so these tall plants will have ample room to grow.


GROWING NOTES

Keep soil moist and well weeded and protect seedlings from birds at planting time with netting or plastic berry baskets, removing before plants get crowded. For large flower heads, space properly so the big plants have room to grow to full size.
