This heavenly scented white petunia has a new name but harks back to 1823 when an explorer plucked it from the mouth of the Rio de la Plata in South America. It does survive rainstorms with no marking and dissolving as some petunias are prone to do, and its sweet scent makes it an essential part of the evening garden.

HOW TO GROW Petunia axillaris

Sowing Instructions

Depth: Surface sow and press in lightly; requires light for germination.
Sprout Time: 7-14 days
Starting Indoors: Start indoors 8-10 weeks before last frost. Keep at 65-75°F.
Starting Outdoors: Direct sow after last springtime frost in zones 8+.
When to Set Outside: After last spring frost.

Placement & Cultivation

Petunia is often planted in containers and is an excellent annual groundcover and bedding plant. Pinch back young plants to encourage branching and more flowers and fertilize regularly. At midseason, trim spreading types, especially if growing in containers, to promote lush growth and flowering. The sometimes extreme heat of summer may cause them to go out of bloom. Moving containers into some afternoon shade is beneficial. An excess of water or soggy soils will result in lanky growth and fewer flowers. Deadhead often for flowers all season.
Final Spacing: 10"
Water Use: Medium Water Use
Watering Details: 1" of water a week. Keep evenly moist but never saturated until established, then water during dry spells, more often if growing in a container.
Soil pH: Acidic to slightly alkaline.
Fertilizer: Fertilize every 3-4 weeks with an organic balanced formulation, or apply a time release fertilizer when planting.
Diseases & Pests: No major problems. Aphids can be dislodged with a stream of water. Tobacco budworm may appear later in the summer. Handpick at dusk when they come out to feed. If necessary, treat with an organically-friendly insecticide, but not a broad-spectrum, as this will negatively affect beneficial insects that parasitize the pest.

Nothing stops these petunias! Thursday, September 10, 2020

Amazing stamina in a petunia. Look as good today (Sep) as when I planted in late March. I have brutally pruned these several times and they continue to flush with lovely bright white petunias.

Scentsational! Sunday, September 13, 2020

Love this old-fashioned petunia. Reminded me of some of the ones found in old Wisconsin gardens...especially in farmyards. Nice fragrance, vigorous grower, a nice addition to my third floor balcony garden. Stood up to Colorado weather: extremes of everything here, wind, rain, hail, drought, etc. Never stopped blooming ...or growing. I prefer it over the newer varietals...will grow it next year with the other old-fashioned climber and put it next to a trellis. Love the fragrance.
