Petunia Seed Collection | Petunia grandiflora & Petunia hybrida

Our Petunia Seed Collection brings together two beloved petunia groups — Petunia grandiflora and Petunia hybrida — chosen for their outstanding garden performance, rich colour palette, and long flowering season. These classic yet ever-popular summer flowers are perfect for gardeners, florists, and balcony growers alike.

Petunia grandiflora

Known for their extra-large, often ruffled blooms, Petunia grandiflora varieties create a luxurious, show-stopping effect. Flowers can reach impressive sizes and come in elegant shades of white, blush, rose, purple, burgundy, and dramatic bicolours. Best suited for containers, pots, and sheltered beds where their delicate petals can truly shine.

Petunia hybrida

Petunia hybrida varieties are strong, adaptable, and incredibly floriferous. They bloom continuously from late spring until frost and are ideal for flower beds, borders, hanging baskets, and window boxes. These petunias offer excellent weather tolerance, vibrant colour mixes, and reliable performance throughout the season.
