A truly unique sunflower of semi-double golden yellow petals surrounding a pollenless green center. Starburst Greenburst’s 10-15cm (4-6) flowers bloom early on 120-159cm (4-6) branching plants. They are eye-catching as the focal point of a bouquet or bunched on their own. High resistance to Downy mildew.
Approx. 25 seeds
Timing:Direct sowrepeatedly after the last frost date. Starting indoors is possible, but does not gain much time. If sunflowers are allowed to get root-bound, they will lack stability at transplant time, and will require staking. Optimal soil temperature for germination:21-30C (70-85F). Seeds should sprout in 10-14 days.
Starting:Sow seeds 5mm-1cm (-) deep. Space dwarf varieties 15cm (6) apart, but give the giants lots of room at 1m (3) between plants.
