How to care
More sun means more flowers — five hours minimum. Keep the soil slightly moist: every other day in dry season, daily under harsh sun. Pinch the tips at 15cm so it branches out and cascades evenly.

Three glazes on the pot shape picked for this species. One tap opens the studio with that setup — change anything from there.
What it is, and who it suits
A petunia cascades into a curtain of flowers that hides the pot entirely, blooming continuously through the season given enough sun and water. This is a seasonal plant — it lives brilliantly for a stretch of time and then fades, unlike most of what is on this list, and a buyer should know that going in. It suits anyone who wants a fast, dramatic burst of colour for a balcony or an event, and is willing to water almost daily in exchange.
Where to put it, and how much room to leave
More sun means more flowers — a minimum of five hours of direct sun a day, and this is an outdoor plant, not an indoor one. A balcony or rooftop that catches sun all day is the right spot. Because the stems trail very long once in full bloom, place it somewhere elevated — a railing, a hanging bracket, a low wall ledge — so the flowers cascade freely without touching the floor or catching on passers-by. A trough is the most common shape for this plant since it holds several cascading plants in one line; a single hanging pot works well too for just one.
The year-round rhythm
The soil should stay slightly moist at all times — every other day in the dry season, and daily under harsh, prolonged sun, because the thin leaves and shallow roots lose moisture fast in direct light. This is the second-tightest watering rhythm in the whole catalogue, after the hydrangea, so it is worth knowing that going in. Pinch the tips at fifteen centimetres so the plant branches out and cascades evenly rather than growing one long straggly vine. Feed weak fertiliser weekly through the flowering season — continuous blooming burns through nutrients faster than almost anything else here. Trim back spent or overly long stems midseason to encourage fresh branching. Since it is a seasonal plant, repotting on a schedule is not really a concern — most people simply replant fresh at the start of the next season.
Which pot suits it
A size M or L trough is the right shape, holding several cascading plants in a continuous sheet of colour — that is the plant's best effect, and a single size S pot cannot produce it. A round hanging pot also works well for a single accent plant. Because the flowers come in bright, varied colours, a neutral glaze like Bone or Tan is the best backdrop, keeping the eye on the blooms themselves; avoid busy patterns since the flowers already cover most of the pot's visible surface. Terracotta suits an outdoor, sun-baked spot well since it drains fast, cutting the risk of rot under near-daily watering.
Three things that go wrong
A long trailing stem with sparse flowers: it was never pinched when young — trim it back now and it will branch and rebloom within a week or two. Yellowing leaves dropping near the base: usually rot from standing water or a pot lacking drainage — check the bottom hole and the saucer. Flowering gradually tapering off despite steady care: this is often simply the natural end of a seasonal plant's life, not a care mistake — with a petunia, replanting fresh each season is more normal than trying to revive one past its peak. This species is pet-safe.
