Dekko™ Pinwheel Purple Petunia

Dekko™ Pinwheel Purple is a spreading annual petunia with purple bicolor flowers. Syngenta identifies this exact selection as product 70099034 and lists an 8–12-inch height, 18–22-inch spread, full sun, and spring-to-summer flowering. It can fill the edge of a sunny bed or trail from a container, while its patterned flowers distinguish it from the separate Dekko Purple selection. [Syngenta Flowers](https://www.syngentaflowers.com/ams/product/flower/70099034) ## Growing conditions Use full sun and moist, well-drained soil. University of Illinois Extension describes petunias as half-hardy annuals and reports reduced flowering in very heavy soil. Check pots and baskets frequently in warm weather; water when the mix begins to dry and let excess drain. Allow room for the 18–22-inch spread, and keep the plant out of shade from taller neighbors. [Illinois Extension](https://extension.illinois.edu/flowers/petunia) ## Maintenance Water during dry spells, especially in containers, and remove damaged growth. If stems stretch late in the season, light pinching can help maintain a tidy outline. The exact Dekko product page also links a series sell sheet listing this selection alongside the separate Dekko Purple and Lavender Eye products.
