Blue Ray - Petunia

Blue Ray is a named Petunia hybrida selection for seasonal flower display. Petunia flowers are typically solitary and trumpet-shaped, with a broad flowering season from late spring into autumn; the exact performance of a named selection depends on its own growing conditions.

Illinois Extension recommends full sun and moist, well-drained soil and describes a wide range of colors and growth habits across the group. Use Blue Ray’s own label when choosing a color combination and spacing; group-level descriptions do not establish its exact color pattern, mature dimensions, or habit. ## Maintenance Do not let the root zone stay waterlogged, and check container moisture as conditions change. The RHS has evaluated watering approaches for container plants including petunias, a useful reminder that pot size and weather affect how often a container needs attention. Late-season pinching can help petunias stay compact and flowering.
