Blanket® Double Chardonnay - Petunia

Blanket® Double Chardonnay is one of the named double-flowered selections in Green Fuse Botanicals’ Double Blanket® petunia group. It is a summer bedding and container petunia; the group’s flowers and growing habit are described across Blanket® sources rather than as separate cultural specifications for each color. ## Flowers and garden use Green Fuse lists Chardonnay among the Double Blanket® varieties and includes Double Chardonnay among Blanket® cultivars in its catalog. The Blanket® group is described for summer color in beds and large containers, with double forms noted as self-cleaning. Its catalog gives a general height of 6–8 inches and a 36-inch spread; these are series-level figures, not a color-specific measured difference. The [Double Blanket® plant page](https://green-fuse.com/new/petunia-double-blanket/) confirms the named selection. ## Growing conditions The [Green Fuse Blanket® culture sheet](https://green-fuse.com/new/wp-content/uploads/2026/06/Petunia-Blanket%C2%AE.pdf) recommends a well-drained growing medium and thorough watering followed by allowing the medium to dry between irrigations. It identifies mixed containers and landscape or bedding use and lists 4- and 6-inch pots, hanging baskets, and combination planters. Petunias perform best in sun; NC State’s general garden-petunia profile also allows partial shade. No cultivar-specific USDA hardiness range is stated for Double Chardonnay. ## Maintenance The culture sheet recommends pinching after establishment to encourage branching. For home landscapes, water deeply, allow excess water to drain, and trim dominant stems if they become long.
