Useful tips and information

Unwins Voucher Codes

Unwins is a well known and highly regarded seed company based in Huntingdon in Cambridgeshire that first came into being way back in 1903. It was more than a hundred years ago that William Unwin was showing fellow choristers his sweet peas and thereafter sold his first sweet pea seeds. His venture led to his hybridising of sweet peas to produce a range of colours. William Unwin and then his son Charles went on to become the nation’s leading sweet pea breeders of the 20th century.

Soon Unwins became known for gladioli and then dahlias, edible peas and tomatoes as well. Today the company has the largest share of the UK amateur seed market. The Times newspaper described the company as "a firm that has grown ... to become one of the most familiar features of Britain’s horticultural landscape". Read on to know more about shopping from the online seed store, and to know about free discount vouchers that will help you save on your garden purchases.
