OSC Seeds Sunflower Cherry Rose Pkg.

Approximately 15 seeds/package

The fastest maturing sunflower we have seen is at only 40 days to flower. A great cut flower with beautiful cherry-red flowers with lemon-tipped petals. Single stem. Plants grow to 150 cm tall. For all sunflowers, to avoid drought stress, fertilize with 15-5-15, or a 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 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.

Easy to grow. In late May, choose a sunny site with well-draining soil and sow seed about 6-12 mm deep, and 7.5-10 cm apart. Thin or transplant seedlings to 30-45 cm apart. Seed can be started 2-3 weeks early indoors using plantable peat pots or Jiffy 7’s, at 21°C. Plant in full sun, keep evenly watered and fertilize twice during the season with a granular 15-5-15 or equivalent. Germination occurs in 5-10 days.
