Petunia grandiflora Double Cascade Blue

The 'Double Cascade Blue' Grandiflora Petunia is a remarkable variety of Petunia. Its long trailing stems are covered in a cascade of large double flowers with a deep midnight blue colour from June to the first frost. It resists rain remarkably well—ideal for containers, hanging baskets, and borders or ground cover.

It is a highly appreciated plant of excellent ornamental value, which owes its success to its generosity and the length of its flowering period.

The 'Double Cascade Blue' Grandiflora Petunia has a trailing habit, reaching a height of 30 cm (12in), and produces long and floriferous stems. You can plant it in the garden, along borders or in the middle of a flower bed, or in pots, containers or hanging baskets where it will look stunning on its own or accompanied by Angelonia, Nemesia, Dichondra or even with Holcus mollis for a modern and contrasting effect.

Native to South America and belonging to the Solanaceae family (like Ornamental Tobacco but also... the potato!), the petunia, or Petunia x hybrida, is an annual herbaceous plant. It bears charming bell-shaped flowers on elongating stems, with the size and colour varying depending on the variety. Its leaves are slightly pubescent, with smooth edges and dark green. It flowers from June onwards and lasts until the first frost.

The petunia thrives in sunny and sheltered positions. It should be planted in rich, light and well-drained soil or substrate. Its cultivation is easy, but it requires a lot of water.

To encourage and support its long flowering period, it is advisable to regularly remove faded flowers and provide a potassium-rich fertiliser, especially in pots and containers, to promote the appearance of new flowers.
