Description

The Cascade Extra' Petunia Mix is a trailing variety with long stems covered in many large flowers in a beautiful assortment of colours from June until the first frost. It is perfect for hanging baskets and containers, as well as flower beds or ground cover. It is a highly valued plant for its generosity and the length of its flowering period.

 

The Cascade Extra Petunia has a trailing habit with long and floriferous stems. It can be planted in borders, flower beds, or pots, 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.

The petunia is native to South America and belongs to the Solanaceae family (like Ornamental Tobacco and... potatoes!). It is an annual herbaceous plant with elongated stems that bear charming bell-shaped flowers of various sizes and colours, depending on the variety. Its leaves are slightly pubescent, with smooth edges and dark green. It blooms from June onwards and lasts until the first frosts.

 

The petunia thrives in full sun and sheltered from the wind. It prefers rich, light, and well-drained soil or substrate. It is easy to grow, but it requires regular watering. To encourage and support its long flowering period, it is important to regularly remove faded flowers and provide a potassium-rich fertiliser, especially for potted plants and hanging baskets, to promote the appearance of new flowers.

 

Attention: seeds are reserved for highly experienced gardeners accustomed to sowing very fine seeds. These seeds are as fine as dust, barely visible to the naked eye.

Planting and care

Sow petunias on a good sowing compost surface from February to April and press gently. Cover the seeds lightly with a thin layer of vermiculite or sieved compost. Place the bowl in a propagator (or enclose it in a polythene bag) or above a radiator at a temperature of 21 to 25°C. Keep the soil moist but not soggy. Light facilitates germination, which generally takes 10 to 21 days.

Once the young petunia plants are large enough to handle, transplant them. Gradually acclimatise the plants to cooler conditions until they are strong enough to be moved outdoors once all risk of frost has passed. Transplant them into well-drained soil at a distance of 30 cm or grow them in pots or window boxes.
