Petunia Seeds

Petunia seeds have been the subject of an enormous amount of breeding work in the last 50 years – it’s no wonder so many of us have grown to love them! These British garden classics are some of the most popular and widely grown container flower plants and bedding flower plants, giving masses of jewel-like blooms in a wonderful assortment of colours – romantic pinks, reds, purples, pastel hues, and enchanting bicolours.

There are so many wonderful petunia seeds to choose from at Fothergill’s. Multiflora petunias are very versatile and weather-tolerant, suited to all types of garden display, while Grandifloras grow the largest, showiest blooms and are perfect for pots. Browse our fantastic range of petunias below and find the best variety for your garden.

Why Choose Our Petunia Seeds?

Petunias are wonderful flowers to grow from seed. Some grow into large mounds of eye-catching blooms, while others have a trailing habit, cascading beautifully over the edges of hanging baskets and window boxes. Many varieties of petunia are “self-cleaning”, meaning they shed their spent flowers all on their own, saving you the task of deadheading. 

To grow petunia seeds, sow them indoors on a warm kitchen windowsill. Introduce your petunias to the outdoors gradually after the last frosts, choosing a sunny, sheltered location. Use a good-quality plant fertiliser, and your petunias will reward you with months of fantastic colour, blooming from spring to autumn!

Petunias pair well with geranium seeds and begonia seeds in hanging baskets, offering a delightful mixture of brightly-coloured blooms.
