Petunia Seeds

Petunia Seeds

Petunia seeds are a gardener's delight, offering a spectacular array of colours for borders, pots, and hanging baskets. At D.T. Brown Seeds, we offer a diverse selection of petunia flower seeds to brighten up any outdoor space. These popular half-hardy annual seeds bloom prolifically from late spring to autumn, with large, trumpet-shaped flowers in shades of white, pink, red, and purple. 

Whether you choose single or bicoloured flower seeds, striking veined patterns, or glorious fully double blooms, our petunia seed collection offers something for everyone. These modern resilient varieties won’t suffer in poor weather, meaning you can enjoy their vibrant displays even through rainy summers. View our full range of petunia seeds below.

Growing Petunias from Seed

Sow your petunia seeds indoors from January to March, maintaining temperatures of 20-25°C (68-77°F). Once germinated, your seedlings will thrive in bright conditions, ready to harden off in late May and plant out from June.

Petunias flourish in light, well-drained soil and full sun, rewarding you with a continuous display of velvety flowers through the warmer months. Our trailing flower seeds, like the popular petunia Rapide Mixed F1, are perfect for cascading over container edges. Our Multiflora strains deliver an abundance of medium-sized flowers, whilst our Grandiflora petunias boast large, show-stopping blooms. 

With regular watering, deadheading, and shelter from wind, your petunia seeds will develop into a stunning floral showcase, blooming until October. For those who prefer a head start, we also offer a selection of young petunia plants.
