Description

(Petunia superbissima). Massive white and pink tinted blooms with dramatically veined throats and heavily ruffled edges make Alba stand out in the garden. We love these compact plants, which reach just 9 inches tall and 28 inches wide and smothered in huge 5-7 inch blooms. This variety comes from Černý Seed Company in the Czech Republic. It is extremely attractive to pollinators and produces delicious edible flowers. At the Baker Creek test kitchen, we included the blooms in a delicious cherry-almond flavored beverage!

Growing Tips, Tricks and FAQs

Growing Tips

Superbissima Giant Alba petunia thrives in well-draining, fertile soil with a pH between 6.0 and 7.0. It needs full sun for the best flowering. Regular deadheading (removing spent flowers) encourages continuous blooming, and pinching back young plants results in bushier growth. Petunias are typically grown as annuals, but they can be perennial in frost-free climates.

When to Grow

Start petunia seeds indoors 8-10 weeks before the last expected frost to get an early bloom. Transplant seedlings outdoors only once all danger of frost has passed and nighttime temperatures remain above 50 F. In warmer regions, petunias can also be directly sown into the garden in early spring or fall. Learn about your area’s hardiness zones and first/last frost dates in our blog post ‘Our Experts Answer Questions, Share Resources.’

How to Sow and Plant

Sow seeds on the surface of moist soil—they require light to germinate, so do not cover them with soil. Maintain a temperature of 70-85 F for best germination, which usually takes 7-14 days. Keep the soil consistently moist but not waterlogged. Once seedlings have developed several true leaves, transplant them into larger containers or directly into the garden, spacing them 10-12 inches apart to give room for their large blooms.

How to Grow

Water petunias about once a week and avoid overwatering to prevent root rot. Fertilize with a balanced liquid fertilizer every 2-3 weeks to encourage more flowers. If plants become leggy, trim them back by one-third to encourage fresh growth. In extremely hot climates, petunias may slow blooming, but providing light afternoon shade can help reduce heat stress. Removing spent flowers and occasional light pruning will keep the plant looking full.

How to Save

  • 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.
