Michigan Petunias

Few plants pour out color like the Petunia, its trumpet blooms cascading nonstop from containers and beds all summer long, a Michigan porch and garden staple.

About Petunias

The Petunia is the tireless color-maker of the Michigan summer: soft, trumpet-shaped blooms in lavender, deep purple, magenta, white, and endless bicolors, tumbling out of hanging baskets, window boxes, and garden beds from June until frost. Where many flowers have a moment, petunias simply keep going, mounding and trailing and reblooming through heat and rain alike. They are the plant that makes a front porch or a market stand feel like high summer.

Garden petunias are hybrids in the genus Petunia, tender relatives of the tomato from South America, so in Michigan they are grown as warm-season annuals started fresh each spring. Our growers raise them as vigorous, well-branched plants ready to pour color into containers and beds, and they truly hit their stride in the long, warm days of a Michigan summer.

Petunias are prized above all as a garden and container flower rather than a long-stemmed cut, though their bright, fragrant blooms are lovely tucked into a short posy or a table arrangement. Whether you are filling a porch pot, a wedding-venue container, or a sunny bed, they deliver more color for the effort than almost anything else we grow.

Forms & Varieties

Petunias come in several habits and flower sizes, each suited to a slightly different spot in the garden.

Grandiflora

The largest, showiest blooms, spectacular in containers where you can appreciate their size up close.

Multiflora

Smaller but more numerous flowers on tough plants that shrug off summer weather.

Spreading and trailing types

Vigorous cascading petunias that spill from baskets and window boxes all season.

Milliflora and novelty

Miniature-flowered and unusual patterned petunias, from starry bicolors to deep near-black shades.

Care & Vase Life

  • For plants and baskets, water consistently and feed regularly, since petunias are hungry, thirsty growers.
  • Pinch or trim leggy stems back midseason to keep the plants full and blooming.
  • Deadhead spent blooms on older varieties to encourage continuous flowering.
  • Give them a sunny spot; petunias flower best with at least six hours of direct sun.
  • For any short cuttings, recut the soft stems and place them in fresh water right away.

Petunia FAQs

Are petunias sold as cut flowers or plants?

Mostly as plants and containers. Petunias have soft, short stems, so they shine as garden, basket, and container color rather than as a long-stemmed cut, though their blooms are lovely in a short posy.

How do I keep petunias blooming all summer?

Give them full sun, water and feed them consistently, and trim back leggy growth midseason. On older varieties, deadheading spent flowers keeps new blooms coming right up to frost.

Do petunias come back every year in Michigan?

No. They are tender annuals here, killed by our winters, so our growers start fresh plants each spring for the new season.

Are petunias good for event and venue color?

Yes. Because they bloom nonstop and travel well as potted plants and baskets, petunias are a favorite for filling venue containers and beds with dependable summer color.
