Madness® Blue Vein Petunia

Madness® Blue Vein is a floriferous petunia selected for its blue-veined flowers, with a mounded, upright plant form. PanAmerican Seed lists spring-to-late-summer flowering, sun exposure, a height of 10–15 inches and a width of 10–12 inches ([official plant details](https://www.panamseed.com/Products/048600864000745/petunia-madness-blue-vein/)). ## Garden Use Its branching habit and abundant 3-inch blooms create a full display in garden plantings and landscape color schemes. The blue-veined selection can add a defined cool-toned accent among white, pink or warmer annual flowers while keeping a relatively compact footprint. ## Growing Conditions Choose a sunny site with moist, well-drained soil. The exact product listing describes a well-branched plant and a broad color range selected for performance; Illinois Extension recommends full sun and moist, well-drained soil for petunias generally ([petunia care guide](https://extension.illinois.edu/flowers/petunia)). ## Maintenance Water during dry weather to maintain even moisture, especially in containers, and allow excess water to drain. Remove faded flowers and pinch lightly late in the season if the plant becomes leggy; avoid heavy soil that stays saturated.
