Thanks to its vigorous, bushy growth and large flowers, this petunia is ideal for gardens, patios, and balcony boxes. The plant blooms profusely from late spring until the first frost, making it a long-lasting color and eye-catcher in summer.

Description and features

Petunia hybrida grandiflora 'Sophistica® Blackberry' forms a compact, bushy plant about 25–30 cm tall. The flowers are large (up to 8–10 cm), trumpet-shaped, and deep dark purple, almost black, creating a striking contrast against the dark green foliage.

Cultivation and care

Petunia hybrida grandiflora 'Sophistica® Blackberry' is easy to grow with a few basic conditions:

• Sowing: Sow indoors in February–March or plant out plug plants after the last frost.

• Position: Full sun for optimal flower development; light shade is possible but reduces flowering intensity.

• Watering: Water regularly, especially during dry periods; avoid stagnant water around the roots.

• Fertilization: Use a liquid fertilizer for flowering plants regularly to encourage profuse flowering and compact growth.

• Care: Deadheading (removing spent flowers) promotes new flower formation and keeps the plant neat and compact.

With this care, 'Sophistica® Blackberry' will grow into a lush, richly flowering and elegant summer bloomer.
