Prima Vera

Breeder:
Dummen
Summary:
In Florida, the most notable feature of this cultivar was that the plants may have had the strongest stems and best upright growth in the trials. Stem strength was quite good at the other locations, but not exceptional. Bracts are a dark red but are brighter than Premium Red. Size was medium to large in FL and NCSU trials but small to medium in Ontario. Bracts are slightly wavy rather than flat like Premium. There was some variation in the appearance of the plants. Some had lighter bract color, some had more non-uniform shoot elongation and some had bracts with longer petioles, which created a more open look in the centers. Also, some of the plants had small stray tertiary bracts that pointed upright in the middle of the cyathia, producing an unkempt appearance. Plants flowered Nov. 17 at NCSU and Nov. 22 and Nov. 26 at 62° and 66°, respectively, in Ontario. Plants held cyathia well and did not develop bract edge burn when held in the greenhouse past flowering. Prima Vera showed the best potential for growers in the Ontario trials.
