Petunia x hybrida

Common Name(s):

Phonetic Spelling
peh-TEWN-ya HYE-brid-ah
Description

Garden Petunia is an annual in the nightshade family that blooms continuously throughout the summer until frost and is one of the most popular bedding plants.  Seeds can be sown in January-March under glass as they require a germination temperature of 72-75 degrees but many people purchase plants in six-packs from local nurseries.  Pinching purchased plants back before transplanting them will help them maintain a bushy habit.  

Plant in full sun to partial shade and light and well-drained soils. While it can survive in heavy shade, the blooms will suffer. Deadheading provides optimal performance and increased flower bud production.  Leggy plants should be pinched back.  Plants may be overwintered indoors in a bright location away from heated air.

This plant has moderate drought tolerance, is seldom damaged by deer and does excellent as a bedding plant and in containers.  It can tolerate poor soils as long as they have good drainage.  Plant in beds and border fronts, along edges, in containers, or hanging baskets, window boxes, or in interior sun rooms in the winter.

The major groupings of hybrid petunias are:

Cascading hybrids- Cascading stems best for hanging baskets or ground covers

Grandiflora hybrids- Large showy flowers up to 4” wide

Multiflora hybrids- Smaller flowers 2" wide but more abundant than Grandiflora

Quick ID Hints:

  • Funnelform flowers
  • Anthers yellow
  • Decumbent herb with sticky pubescence

Insects, Diseases, and Other Plant Problems:   Aphids, flea beetles, slugs, and snails are insect problems.  Root rot, gray mold, and tobacco mosaic virus are disease problems. Some cultivars have shown poor resistance to phytophthora root rot or stem rot. See Phytophthora Root and Crown Rot in the Landscape.
