Rudbeckia Hirta ‘Goldilocks Improved’

Rudbeckia hirta 'Goldilocks Improved'

Trial: Annual

Years Trialed: 2003

Good Qualities:

Double flowers (6); Very showy and uniform, fast to flower, many petals; 85 days from seed to blossom, perfect filler size for bouquets, excellent 2 tone gold color with variable petal count, good vase life, good stem length; Butterscotch yellow petals; Would make a good landscape plant; Nice sized, stems are sturdy; Tall strong plants; Good vase life; Beautiful flowers, great rebloomer; Easy; Cheerful color; Great, good novelty cut, 4-6 usable stems, 20 inches long; Flowers were 2 ½ inches across.

Problems:

Too short (3); My customers have no interest, deer love rudbeckia; Some plants died off in the row, they didn’t seem to have very consistent growth; excessive rain could have been a problem, but I would say more humidity on leaves than wet roots caused the problem; Raggy looking, did not hold up well (hydration); Poor germination compared to the other rudbeckias; Too short for use in bouquet work used most of them for “free for Kids” vase at farmer’s market; For me this cultivar was not very uniform and I had a lot of problems with its lodging; Wilted in vase, need to learn about better postharvest techniques; Deer ate every one of them, pulled the entire plant, usually they nip a few rudbeckia so I can only guess ‘Goldilocks’ tastes better than any other variety; Plants did not do well; Poor germination, plants not as healthy as two other rudbeckias trialed.

Comments:

Home garden item; We like this plant/flower; Stems too short, mildew started early in season and plants quit producing or died off; It’s best to treat this as hardy annuals for best and strongest growth – I also grew ‘Indian Summer’, ‘Autumn Colors’ and ‘Prairie Sun’ in same conditions – The other 3 were strong growers and beautiful flowers and I have not found ‘Goldilocks’ to be good; Appears to take 3 degrees of frost without any damage, not as popular as the other rudbeckias grown; Another great flower in need of longer stems; If these plants survive our Zone 4/5 winter (and I hope they will) my second year plants have much better height and yields. (See article in this issue for postharvest testing of this cultivar.)
