Glow Hell's Glow - Petunia

Hells™ Glow is a branching petunia with purple flowers, listed by Westhoff for containers, hanging baskets and landscape planting. Its official profile gives a compact 6–8 inch height and describes flowering from spring through autumn. ## Selection and siting Westhoff identifies the plant as Hells™ Glow (product code Wespehegl), recommends full sun, and gives a 6–8 inch mature height. The page lists 12–18 inches as planting spacing, which is not a mature-width measurement; the existing width estimate is therefore retained separately. [Westhoff: Hells Glow](https://www.westflowers.de/variety/hells-glow/) ## Growing Use fertile, freely draining potting mix or garden soil and water consistently while plants are actively growing. In containers, check moisture frequently during warm, windy weather. General petunia guidance also favors full sun and well-drained soil.

Regularly check hanging baskets and patio containers for drying soil so flowering plants do not remain wilted for long periods.
