The New Italian Petunia That Towers Above the Rest

Bred on the slopes of Mount Vesuvius. It towers, it re-flowers, and it's a cut flower! 

Petunia ‘Allegra F1’ - The Biggest Petunia You’ll Ever Grow!

A revolutionary towering petunia that dwarfs them all - reaching over five feet (1.5m) and flowering for more than 5 months. Bursting with double flowers all summer, Petunia ‘Allegra F1’ is male-sterile, so blooms drop naturally, no deadheading needed. Perfect for cut flowers with over 20 blooms per stem, each reaching up to 12cm wide.

Bedding just got bigger, bolder and better with Allegra F1

Perfect for a big impact display, bringing height and structure to patios, borders and containers.

A breeding breakthrough!

Thanks to its modern breeding, ‘Allegra F1’ re-flowers all summer, for over five months of colour! This male sterile variety means strong stems, strong garden performance and exceptional growth. These towering giants will dwarf traditional trailing and mounding types.

Bring a touch of Italian chic indoors!

Allegra's strong, thick stems make it an exceptional cut flower, particularly in tall vases. With 20 blooms per long sturdy stem, each up to 12cm wide, it lasts a good 7-10 days in a vase. Enjoy it outside then bring it inside. Belissimo!

Ultimate height: 150cm (5ft). Ultimate spread: 75cm (30in).

Petunia ‘Allegra Collection’ contains the following varieties:

  • Petunia 'Allegra Pastel Orchid' – Lavender
  • Petunia ‘Allegra Picotee Velvet' – Deep magenta and white bicolour
  • Petunia ‘Allegra Pure White’ - White

How to Grow
Pot up petunia plants and grow them on in warm frost-free conditions for transplanting later on. Pinch out the growing tip of each stem to encourage branching and form a bushier plant which will produce more flowers later on. When all risk of frost has passed, gradually acclimatise them to outdoor conditions over a period of 7 to 10 days, before transplanting them outdoors into baskets, window boxes and containers in well drained soil, in full sun.

For more information and guidance check out our Gardening Guides.

More Info
Feed and water petunia plants regularly, particularly during hot, dry periods. Regular deadheading of petunia flowers will encourage further blooms to be produced throughout the summer.
