Comments
Editor note: See the Postharvest Report in this issue for vase life and handling information. Similar to ‘Benary Giant Yellow’ (2); Would not choose to grow ‘Sun Gold’ over ‘Benary Yellow’; Benary Giant Series has a better yellow, taller plants ‘ longer stems; While this only comes in yellow, pink and red, the florists really liked them; Stem length may have been better under more favorable soil moisture conditions – This color seemed to be more susceptible to powdery mildew late in the summer than was ‘Sun Cherry’- The powdery mildew seen in early Sept. would have made ‘Sun Gold’ unmarketable but not ‘Sun Cherry’; The yellow was beautiful – It was the deepest, most vibrant yellow of all my zinnias – I would grow these again; One customer came back for a bunch of these yellow flowers several weeks in a row; I would only grow again to see if mildew problem was better – If not, I would try other varieties; Better than the Benary series yellow in bloom size and color – Will certainly plant this again; Hope they give us the whole range of colors eventually, will we ever see a blue zinnia?; Still great in October (Zone 4).
