Description

(Petunia hybrida). This bicolored, bubblegum pink and white petunia has frayed and ruffled edges, making it one of the most cheerful and eye-catching varieties we have ever seen. Plants reach just over 1 foot tall and are smothered with these fascinating 2- to 2.5-inch blooms. This variety was bred in 1934 by Černý Seed Company in the Czech Republic, where it is enjoyed as a bedding or container petunia and praised for its versatility.

Growing Tips: Karkulka petunia thrives in well-draining, fertile soil with a pH between 6.0 and 7.0. It prefers full sun but can tolerate partial shade, though too much shade may reduce flowering. Deadhead spent flowers to encourage continued blooming. Pinching young shoots makes for a more compact growth habit.

When to Grow

Start petunia seeds indoors 8-10 weeks before the last expected frost. Transplant seedlings outdoors once all danger of frost has passed. In warmer regions, petunias can also be sown directly in the garden in early spring or fall. If you’re unsure of your last frost date, consult our blog post ‘Our Experts Answer Questions, Share Resources.’

How to Sow and Plant

Surface sow the seeds, as they need light to germinate. Keep the soil consistently moist and maintain a temperature of 70-85 F for best germination. Once seedlings develop several true leaves, transplant them into larger containers or directly into the garden, spacing them about 6-8 inches apart.

How to Grow

The plants are fairly drought tolerant, although watering consistently once a week is preferable. You can use a balanced fertilizer every 2-3 weeks to help maintain healthy growth and abundant blooms. Petunias are heat-tolerant but may slow blooming in extreme summer temperatures; light afternoon shade can help reduce stress.

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.
