Some info about petunias

They are actually evergreen perennials, hardy to Zone 9A. Very common and suitable to use as “Annuals” in colder climates. Most varieties available are hybrids: Petunia x hybrida,

Propagation
• Vegetative: propagated by stem cuttings. Reasons could be the plant produces sterile seed or doesn’t come true from seed. Patent pending etc. These are usually available as plants only
• Seed varieties are usually available by single variety or selected mixes. These are available as plants and/or seed packages

Daylight Neutral
• If the petunia is daylight neutral or semi-neutral, it will develop flower buds during short days in early spring and late fall. (less than 12 hour daylight)

Deadheading
• Many new varieties are “Free-Flowering”, which means they do not need to be deadheaded to encourage new flower bud formation. Some do need to be tidied up if the flowers don’t shed off.

Color
• Petunia “Purple” is more of a Magenta color. Petunia “Blue” looks deep blue-lavender, or dark royal purple. “Morn” is tri-color with the base color + White throat + Yellow center. Many colors change with temperatures and sunlight conditions. Bi-Colors, such as Sophistica Lime Bi-Color may have an irregular pattern

Bloom Patterns
• Star is usually base color with a White star. Petunia x hybrida Phantom is unique with near-Black base color and a Yellow star
• Picotee, Frost, Hulahoop all have base color with White edge. Supertunia Pretty Much Picasso is a Fuchsia base with Lime Edge
• Vein, Lace, Crystal and Ice are typically base color with dark veins. Daddy series are all veined.

Growth Habit
• Upright: about the same H x W good for planters or in ground
• Round or Bubble: slightly wider than high to give a round display
• Mounding: keeps height in the center, good for planters or in ground or more compact looking basket
• Mounding Spreading/Trailing: Stays about 10” to 14” high with 2’ + stems. Best choice for hanging basket
• Spreading/Trailing: Long stems, usually only 6” to 8” high with over 2’+ stems. Will sprawl in ground and drape in a basket
• Rule of thumb for # plants per basket: The number of plants is about half the diameter. So a 12” basket will do well with 5-6 plants (excluding Tidal Waves).

Flower Size
Milliflora: less than 2” small
Multiflora: about 2.5” medium
Floribunda: about 3” large
Grandiflora: 3.5” to 4” extra-large

Determinate versus Indeterminate for amount of flowers per stem
99.9% of the "Double" Flower petunias have one bloom at the end of the stem
Most of the Single Flower petunias are Indeterminate and have multiple blooms along the last section of the stem

“Compact” The plant is not small. Compact refers to a tight growth habit. Short internodes
“Dwarf” usually refers to the plant not the flower
“Vigorous” Strong stems and often longer internodes. Usually spreading or trailing types

I used a lot of these terms in the ATP database. Hope it helps

Joanne, this would be good information to post in the database. Or at least a link to it.

Awesome post, Joannabanana. I am in zone 7 and I grow them as annuals. Sadly, my tulips grow as annuals, too. smh. that one I don't get.

Beautiful photos and great info, Joanna. Petunias don't do well for me. They really dislike the summer heat in Oklahoma. Wonder if there are any cultivers that are more heat tolerant?

Beautiful pictures and great information, Joanne!

I was wondering how I might have missed this before and then I realized that I had joined in July of 2012. Maybe I hadn't fully explored all of the threads back then and am just now finding it Big Grin

Great info!

I started a large container of the Wave blue you posted on my mom's porch and it went crazy. Cars slowed down, seriously. It fizzled out early and was replaced with a Wave pink that did well but never compared to that first "blue". At the same time I started another pot with "conventional" petunias. A waxy black in the back with a draping black/yellow out front. Plain little German Brick but I do plant to impress. Cars again slowed to take in the view. I went to check the mail one day and startled a woman with a huge camera and macro lens zapping pictures.

She started to explain that she lived 20 doors down and walked every day. Ring finger filled (just my luck). But I still opened the back gate and let her shoot flowers and veggies. Gave her some 'maters and peppers to go.

Funny how you meet people, Petunias draw folks in. I've made more money from Impatiens and annual Begonias but I believe Petunias are a more inviting bloom. Definitely a "front porch" welcome mat of sorts.

I'll continue to sample and enjoy for years.

I love petunias!!
I buy them every year for my flower garden. They don't last all year in my neck of the woods, but that's OK. It makes me happy planting them in different places each year. Lovey dubby
Lord please let this seed not be a weed!
