Hanging baskets, window boxes and garden-center flats are full of trumpet-shaped flowers that look alike at first glance. If you are wondering whether yours is a grandiflora petunia, a trailing Wave type or actually a Calibrachoa, our petunia identifier sorts it out from one photo. You also get the care basics that keep the plant flowering until frost.
How It Works
Take a close shot of one flower from the front plus a side view of the stem, so the AI can see flower width, the throat veining and how sticky or hairy the leaves look. Shoot in shade or on an overcast day to keep purple and red tones accurate. The result names the group or likely series and lists watering, deadheading and feeding advice.
Key Benefits
- Tells petunias apart from the smaller million bells (Calibrachoa) sold beside them
- Recognizes grandiflora, multiflora, milliflora and spreading types by flower size and habit
- Helps you match a basket you loved last year when buying replacement plants
- Explains why stems get leggy in midsummer and how to cut them back
- Free to try online, one identification per day, no account needed

Frequently Asked Questions
Common questions about petunia identifier
Upload a front-facing flower photo and a shot of the foliage; the AI estimates the type (grandiflora, multiflora, trailing) and points out if it is really a Calibrachoa or Nicotiana.
Petunia flowers are usually larger (2–4 inches) with sticky, hairy leaves, while Calibrachoa flowers are about an inch across, more numerous and have smaller, less sticky leaves.
Petunias are listed as non-toxic to cats and dogs by the ASPCA, though eating a lot of any plant can upset a pet's stomach.
Heat, lack of fertilizer and seed formation slow blooming; trimming stems back by a third and feeding every one to two weeks usually brings a new flush.
They are tender perennials grown as annuals in most of the US, UK and Canada and die with the first hard frost.
