Tattoo™ Blueberry Vinca

Tattoo™ Blueberry is a compact, upright vinca grown for violet flowers and a mounded, well-branched habit. At 10–14 inches tall and 6–8 inches wide, it fits sunny containers, borders, and mass plantings. ## Flowers and form The [PanAmerican Seed profile](https://www.panamseed.com/Products/063707916007898/vinca-tattoo-blueberry/) identifies Blueberry as *Catharanthus roseus* product PAS1357700 and lists late-spring-to-late-summer bloom, an upright habit, and 10–14-inch height by 6–8-inch width. The breeder describes its unusual color for combining with red-and-white plants in heat-loving blue mixes and notes that Tattoo petals carry dark purple brush strokes. In a [Penn State Flower Trials entry](https://agsci.psu.edu/flower-trials/trial-year/2020/plant-name/vinca-catharanthus--tattoo-blueberry-seed), Tattoo Blueberry flowers are recorded as violet. Tattoo colors show stronger contrast in warm conditions with moderate light and may lighten under hotter, brighter conditions. ## Siting Grow in full sun to light shade in soil that drains well. [North Carolina Extension](https://plants.ces.ncsu.edu/plants/catharanthus-roseus/common-name/annual-vinca/) describes Catharanthus as a heat-blooming bedding plant for borders and containers. The [University of Florida IFAS guide](https://ask.ifas.ufl.edu/publication/fp112) recommends well-drained soil and reduced irrigation after establishment. ## Maintenance Use as a warm-season annual where frost occurs. Water newly planted vincas until they establish, then water only when rainfall and soil moisture call for it; saturated roots are prone to disease. Compact modern hybrids generally do not need pinching or deadheading. Remove damaged stems as needed and replace the planting after frost in cold-winter climates.
