OSC Seeds Thunbergia Black-Eyed Susan Vine Pkg.

Approximately 25 seeds/package (40 seeds/gram)

A very useful climbing annual vine for training on fences, trellises or for use in hanging planters and window boxes, where they can trail down. Flowers are a mix of orange, yellow or white, all with a black centre. A very pretty effect! Self-twining vines can grow to 2 m in height.

Soak seed overnight in room temperature water, then sow the seeds in Jiffy 7’s and keep at 24°C for the 14-day germination period. Grow under lights at a cooler temperature of 20°C before hardening off, and transplanting outside after all danger of frost has passed. Seed can also be directly sown outside in late May after first soaking in a wet paper towel for several days. Self-twining vines can grow to 2 m in height. A few hours of afternoon shade is very beneficial in hot summer areas. Keep evenly watered and feed with a water-soluble 20-20-20 or 15-30-15 throughout the summer. Germination occurs in 10-14 days.
