Carpet Rose - Petunia

Carpet Rose is a named selection in PanAmerican Seed’s Carpet multiflora petunia series. The breeder describes Carpet as heat tolerant and free flowering, with excellent branching, mid-sized blooms, and a compact shape that holds longer in high-heat conditions. ([PanAmerican Seed Carpet series](https://www.panamseed.com/PdfAssets/pdfpage.aspx?pdfid=13)) ## Site and seasonal display Hybrid petunias are commonly grown as half-hardy annuals. Illinois Extension recommends full sun and moist, well-drained soil and describes a wide range of flower colors and habits across the group. The RHS botanical profile notes solitary, trumpet-shaped flowers and flowering from late spring into autumn. These general group traits help plan a seasonal display; use Carpet Rose’s own label for the selection’s exact color and spacing.

The RHS container study includes petunias and compares watering methods for containers. Illinois Extension notes that occasional late-season pinching can help petunias stay compact and bloom well, while heavy soil can reduce flowering.
