Trial: Annual

Year Trialed: 2004
Year of Trial: First (from 2004 report)

Zinnia 'Oklahoma Yellow'

Good Qualities

Great bright color (11); Very productive (5); Strong stems (2); Long stems, tight flower heads, long produce period (8 weeks so far); OK hardiness; Nice double flower; Good uniformity; Did not begin to pick all the potential stems because when our’Benary Giants’ started to produce, we stopped picking; Impressively pest-resistant compared with other zinnias, most saleable stems by color, nice formation; Good doubleness, more useful than ‘Oklahoma Gold’; Fully double small flowers; Canadians are not great zinnia lovers in fresh, great as yard plant; A nice yellow to go with the ‘Envy’ and ‘Benary’s Giant White’ provided a subtle range of soft colors; Mostly double flowers; given a better understanding of this little guy, we may be able to make money with it.

Problems

Powder mildew (3); Flower size too small (2); No problems (2); We did not like this particular yellow color in our mixed bouquets; it just didn’t seem the right yellow; Outdoors there were many short stems of limited marketability; Multi branching made it difficult to cut for less experienced cutters; Variable stem length even with early pinching; Small, branching flowers and stems.

Postharvest

Hydraflor, Floralife; Water only, no cooler, morning cutting; Needs work. Editor’s note: see separate postharvest article in this issue for more information.

Comments

Similar to other Benary zinnias; Will definitely plant again; Sowed directly into a 128 cell tray in greenhouse on 4/16/04, harvest period from 7/8 to 7/19/04 though could have gone much longer; Very impressed with this flower; Healthy plants in a year of disease producing weather; This made a gorgeous landscape plant; Most of the test was spent trying to figure out how to handle this compared to bigger zinnias with longer stems; by the time we figured out how, when and where to cut, they were fizzled; Will not plant again, takes too long to harvest; flowers, some single, some double.
