Blanket® Blue Star - Petunia

Blanket® Blue Star is a spreading multiflora petunia with deep purple flowers marked by a white star-shaped center. Green Fuse lists it in the Blanket series, which is selected for continued color through summer heat. ## Garden Use Blanket® Blue is a spreading multiflora petunia with blue-violet flowers; Blanket® Blue Star carries deep purple flowers with a contrasting white star. Green Fuse lists both selections in its [Blanket series](https://green-fuse.com/new/petunia-blanket/) and describes the series for garden beds and containers, with color that continues through summer heat. The catalog gives a mature height range of 6–8 inches and a spread range of 30–36 inches; those ranges are retained without choosing a single numeric point. ## Site and Water Petunias perform best in full sun and well-drained soil. The [Green Fuse culture sheet](https://green-fuse.com/new/wp-content/uploads/2026/06/Petunia-Blanket%C2%AE.pdf) recommends watering thoroughly, then allowing the soil to dry between irrigations. Its container guidance includes pots, hanging baskets, and combination planters. The [University of Florida IFAS guide](https://gardeningsolutions.ifas.ufl.edu/plants/ornamentals/petunias/) also recommends full sun and moist, well-drained soil; local heat and drainage affect how often containers need water. ## Maintenance Check pots and beds regularly during hot weather, since containers dry faster than garden soil. Water deeply when the mix begins to dry, and avoid leaving roots in saturated soil. Pinch or trim dominant stems after transplanting if a fuller shape is wanted; remove spent flowers as needed to keep the planting tidy. Watch for aphids, thrips, and whiteflies, and avoid prolonged wet foliage or waterlogged media.
