Shock Wave™ Yellow - Spreading Petunia

Shock Wave™ Yellow is a named color selection in PanAmerican Seed’s Shock Wave spreading-petunia family. The official Wave guide lists Yellow as a distinct Shock Wave variety, while Ball’s plant detail describes the family’s mounded, spreading growth, petite flowers, and strong fill for sunny beds, baskets, and containers. ## Growing Plant in full sun and use moist, well-drained soil. In containers, provide drainage and check moisture regularly in warm or windy weather. Leave room for spreading stems so they can fill around neighboring plants without covering smaller companions. PanAmerican lists Shock Wave Yellow among its exact Wave varieties, and Ball’s Shock Wave profile describes the line’s spreading habit and outdoor garden use. [PanAmerican’s guide](https://www.panamseed.com/documents/catalogs/17196_PIG_ENG_LR.pdf) and [Ball’s plant detail](https://info.ballseed.com/WEBTRACKPLANTINFO.ASPX?PHID=048605220001226&env=P) support these series-level traits. ## Maintenance Keep moisture even and remove tired growth as needed. [Illinois Extension](https://extension.illinois.edu/flowers/petunia) notes that occasional late-season pinching can help petunias stay compact and continue blooming. This annual petunia is suited to seasonal color displays in sunny sites.
