Black Eyed Susan Vine Thunbergia Seeds 6270. 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 (6′) in height.
How to Grow
40 seed/gram. Soak seed overnight in room temperature water then sow seeds in Jiffy 7’s – keep at 24 C (75 F) for the 14 day germination period. Grow on under lights at a cooler temperature of 20 C (70 F) 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 (6′) 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.
