Surfinia® Heavenly Blue - Petunia

Surfinia® Heavenly Blue is a blue-flowered petunia with a rounded, semi-trailing habit. It suits sunny containers, hanging baskets, window boxes, and garden beds, where the flowers create a cool-toned accent through the warm season. ## Form and placement Suntory lists plants at about 8–12 inches tall and 18–24 inches wide. Allow room for the plant to mound and spill slightly over container edges. The [official Heavenly Blue detail page](https://suntoryflowers.com/variety/surfinia-heavenly-blue/) identifies the selection, its blue flowers, mature size, and growing conditions. Pair it with white or silver foliage for contrast, or use it as a blue element among other seasonal annuals. ## Growing conditions Plant in full sun for the best flowering; partial sun is also listed. Choose a fertile, well-drained bed or container mix and provide regular water while growth and flowering are active. Containers dry faster than garden soil, so check them more often during warm, windy weather. The [Illinois Extension petunia guide](https://extension.illinois.edu/flowers/petunia) describes general petunia siting and care; the specific size and flower details above come from Suntory. ## Maintenance Remove broken or damaged stems and trim back any growth that becomes uneven. Keep water flowing freely from containers and avoid waterlogged soil. Treat as a seasonal annual where winter frost prevents outdoor survival.
