The breeder reports screening against 36 contemporary aerial Phytophthora strains, including ten highly virulent strains; this resistance reduces risk but does not make plants immune.

Compare current photographs if you want to match a specific shade. ## Growing conditions Plant outdoors after frost in warm weather. [NC State Extension](https://plants.ces.ncsu.edu/plants/catharanthus-roseus/common-name/annual-vinca/) describes Catharanthus roseus as growing in full sun to partial shade and prefers moist, well-drained soil; follow the breeder’s full-sun recommendation for this selection. In frost-prone areas it is grown as a warm-season annual, although it can persist as a perennial in tropical climates. The product page’s zone entry describes tropical hardiness and does not define the full range for seasonal annual use. ## Maintenance Water transplants while roots establish and during extended dry spells, while avoiding saturated soil. Modern Catharanthus hybrids generally do not need pinching or deadheading.
