Comments
Similar to Goldburst (2); Similar to Teddy Bear; No fertilizer or chemicals used. They just kept blooming each week. Customers at Farmers Market looked for these. Other flower growers there wanted to know where I got seed, told her nothing!; Had trouble figuring out when to cut; Long bloom period all August into September; Goldburst is far superior to this cultivar.
