Prima Donna

Breeder:
Dummen
Summary:
These plants had bright red bracts and large centers with many small cyathia. The cyathia had nice, distinctive coloration and were held by the plant as it matured in the greenhouse. Dummen is using the name “Prima” to refer to cultivars that have smaller leaves and bracts, which should allow for less physical damage during shipping and retail handling. The Prima cultivars are not in a “family” and do not necessarily have similar growth habits and appearances. An outstanding feature of Prima Donna is excellent branching with strong stems and upright habit as observed at all three trial locations. Unfortunately, this was one of the first groups of plants to develop bract edge burn spots (Calcium deficiency) in the FL trial. In Florida and North Carolina, there was a small amount of stretch at the end of the crop that caused the plants to have an open appearance as the bracts expanded. In Ontario, the bracts tended to have a wavy margin and were slightly crinkled creating a very untidy bract formation. Plants finished early season and were medium vigor.
