Trial: Annual

Year Trialed: 2008

Zinnia 'Zowie Yellow Flame'

Good Qualities

This one is a hit. I made bouquets with orange safflower, blue annual statice, 5 Zowie, 7 Uproars, they blew out of the farm market I sold to all summer long; Powdery mildew susceptible, therefore spacing is crucial, susceptible to other foliar diseases as well; I usually wait to grow this for end of summer, so perhaps it would be taller if I started earlier; Entire zinnia crop was planted late while I was out of town, this year, I pinched in August and cut back severely in late August which did increase stem length; A favorite!; Did well in greenhouse – used water with a lower EC; bloomed over much of the growing season; We had more rain than usual and cool nights, which caused some rust; I would not grow it again because of the disease problems, compared to other zinnia cultivars I grew, this was the least vigorous and most disease prone.

Problems

Stems too short (10), Small flowers (2); Better as a bedding plant (2); Continual cutting eventually elongates the stems somewhat; Significantly shorter flowers, more botrytis-susceptible in a high tunnel planting than other varieties; Variable number of petals on blooms; Minor Japanese beetle damage; Zinnia meltdown at times; Mildew; Flowers were never big and double; Sprayed for fungal diseases and beetles, bad year for Japanese beetles; Sensitive to our high EC water; We had the usual problem of short holding for all zinnias, problems with Japanese beetles and leaf spot; Poor seed germination, poor seedling vigor, disease prone both in the greenhouse and field.

Postharvest

Plain water (2); Cooler temps, our storage was 68 F and not cool enough, bleach and water alone doesn’t work the best; Surface sterilize stems in a 10% bleach solution, we don’t use floral preservative with zinnias, we avoid keeping them in the cooler; Picked fully developed.
