Do petunias have a fragrance?
This white-flowered hybrid releases an aromatic, sweet-smelling fragrance in the evening to attract insect pollinators, such as hawk moths. “It makes sense that they should time this with when the pollinators will be around.” Imaizumi’s team discovered a major gene that controls when the petunia releases its fragrance.
What does petunia smell like?
The researchers turned to the common garden petunia, a white-flowered hybrid that releases an aromatic, sweet-smelling fragrance in the evening to attract insect pollinators, such as hawk moths.
Why do petunias smell bad?
I never really cared for the scent of any petunias, but these supertunia varieties seem to smell particularly foul. Perhaps it is because they are self dead-heading and the smell comes from the accumulated build-up of spent flowers and leaves decaying in the pot.

Which petunias smell the best?
Why do petunias get sticky?
When tiny insects get onto potato plants’ hairs, they become trapped. This commonly happens with aphids. Although aphids are among the most likely pests for petunias, petunias have something in common with them. The tiny bugs give off honeydew, which is sticky in its own right.
Do petunias need sun or shade?
Site and soil Petunias need at least 5 or 6 hours of good sunlight; they’ll perform even better when located in full sun all day. The more shade they receive, the fewer flowers they’ll produce. Impatiens are a better choice for blooming in shady places.

When do petunias smell the best in the garden?
This is a highly inaccurate method, because flowers express their perfumes at particular times (often morning or evening) and in certain climate circumstances (high humidity, cool air temperature), and usually smell like nothing at all in mid-day hours at the garden centre. However, it can be said that some petunias are more perfumed than others.
Why do white petunias have a strong scent?
It’s known that white P. axillaris emits strong scent after dusk to attract night-flying hawk moths; violet P. integrifolia produces a less intense daytime scent to attract pollinator bees in sunlight. Isolating the scent genes makes it easier to breed new perfumed petunias.
What does LHY do to a Petunia plant?
Imaizumi’s team even discovered how LHY represses floral scent production. It interferes with the activity of ODO1, another petunia gene that promotes the production and release of floral scents. By repressing ODO1 activity early in the day, LHY stops the floral scent assembly line in its tracks.
Are there any petunias that are more perfumed?
However, it can be said that some petunias are more perfumed than others. There are many flower sizes, colours, bi-colours and forms of petunias (spreading hedgiflora, grandiflora, multiflora, milliflora, frilled, double).
