Description

(Petunia integrifolia). A native wildflower of South America with fascinating history. The low-growing, heat-tolerant Petunia integrifolia is floriferous and easy to grow, blooming all summer long. Native to the Ecuador highlands, this plant was traditionally used as a hallucinogenic, with reported sensations of flying or floating. Because the chemicals have not been widely studied, we recommend against ingesting or experimenting with it. We do, however, love it as a versatile bedding or container plant.

Growing Guide

When to Grow

For best results, start seeds indoors 8-10 weeks before the last frost date in your area. Once temperatures stay above 50 F, transplant seedlings outdoors. Since petunias are not frost-hardy, be sure to check local frost dates before planting them outside. If you’re not sure how to do that, check out our blog post ‘Our Experts Answer Questions, Share Resources.’

How to Sow and Plant

Surface sow in a moist seed-starting mix, pressing the seeds gently into the soil. Do not cover them, as they require light to germinate. Keep the temperature between 70-85 F during germination. It typically takes 7-14 days. Once the seedlings have two or three sets of true leaves, transplant them into individual pots. Before moving them outdoors, gradually harden off the plants over 7-10 days by exposing them to outdoor conditions a little more each day.

How to Grow

Transplant petunias 6-8 inches apart in a sunny, well-draining area. Water regularly, allowing the top inch of soil to dry between waterings to prevent root rot. Mulching around the base of the plants helps retain moisture and suppress weeds. To encourage fuller, more compact growth, pinch back young plants by trimming the tips of new growth. Deadhead regularly for continuous flowering throughout the season. Keep an eye out for common pests like aphids and caterpillars.

How to Save Seeds

  • Petunias will readily self-seed in mild winter climates.
  • To save seed, hand-pick the brown seed pods.
  • Take care to collect the seed pods before they burst and spread the seeds across the garden.
  • Store the seeds over winter in a cool, dark, dry place.

FAQ

Why are my Wild Violet petunias getting leggy?

Legginess is often caused by lack of sunlight or infrequent pruning. Pinch back stems regularly to encourage bushier growth.
