Sonic Amethyst New Guinea Impatiens

Sonic® Amethyst is a compact, mounding New Guinea impatiens with violet-purple flowers and green foliage. Syngenta lists this F1 Sonic selection for full shade through part sun, flowering from mid to late spring into summer and reaching 10–14 inches tall and wide. [Syngenta Flowers](https://www.syngentaflowers.com/ams/product/flower/70003738) ## Garden Use Use it in shaded beds, grouped plantings, containers, or hanging baskets, where its compact form and bright blooms add seasonal color. The breeder lists hardiness zone 11a; in colder climates, grow it as a warm-season annual rather than expecting it to overwinter outdoors. New Guinea impatiens perform best in bright shade or partial shade, although they can take more sun if watering is consistent. [NC State Extension](https://plants.ces.ncsu.edu/plants/impatiens-hawkeri/) ## Soil and Water Choose organic-rich soil that drains freely and keep the root zone evenly moist. Containers dry faster than garden beds, so check them regularly. Iowa State advises avoiding both waterlogged soil and dry root balls; adjust watering with weather, exposure, and pot size.

In frost-prone areas, treat the plant as a seasonal display and replace it after cold weather ends its growth.
