Cherry Rose Sunflower Seeds 6165. The fastest maturing sunflower we have seen at only 40 days to flower. A great cut flower with beautiful cherry-red flowers with lemon tipped petals. Plants grow to 150 cm (5′) tall. With all sunflowers avoid drought stress and fertilize with 15-5-15 or similar analysis. Nitrate based nitrogen is better than ammonia based nitrogen. Stop fertilizing when flower buds form. Adequate soil moisture is important at all times and avoid overhead irrigation so as to keep the foliage dry. Space plants far enough apart to ensure good air movement over the foliage. Cool nights help the plant form a good solid stock.
How to Grow
Easy to grow. In late May, choose a sunny site with well draining soil and sow seed about 6-12 mm (1/4-1/2″) deep and 7.5-10 cm (3-4″) apart. Thin or transplant seedlings to 30-45 cm (12-18″) apart. Seed can be started 2-3 weeks early indoors using plantable peat pots or Jiffy 7’s at 21 C (70 F). Plant in full sun, keep evenly watered and fertilize twice during the season with a granular 15-5-15 or equivalent.
