    • Living in the Netherlands, sweetpeas have always been my favourite summer blooming annual. Probably because my grandmother always had a patch growing in her garden, and I loved the smell as a child (and still do).

      This year I have three of your creations growing in my garden, "Erewhon", "High scent" and "Blue shift", and even though all of them look and smell extremely well, I have completely fallen in love with the "Blue shift" variety. So I just wanted to take the time to thank you for all your work on one of my favourite plants. And I am looking forward to any new varieties you'll introduce.

    • "Your seeds have been fantastic. I gave half to my mother last time who is 82 and her house is probably to be demolished. It has been a very stressful time for her and we have had a lot of enjoyment from planting your seeds and then seeing and smelling the beautiful flowers. It has put a bit of spark back in Mum's life and garden."

    • "Last years flowers were most successful. 'Pink Nines had 7 and 8 flowers per stem and were the first out. With white and navy the last, but the navy ones had masses of flowers, mostly four to a stem. I am looking forward to this years flowers."

    Why Us

    Cultivared sweet peas

    Our sweet peas are all grown on supports as opposed to let grow along the ground. By growing on supports any 'off types' can be removed and not allowed to set seed, allowing for only premium blooms.

    Cultivared sweet peas

    Over the last 25 years, we have developed wonderful sweet pea cultivars that combine the weather tolerance and fragrant perfume of old-fashioned types with Spencers larger blossom size and beautiful ruffled form.

    By buying direct from the breeder you are buying mother seed, carefully harvested by hand. In addition you have the opportunity to obtain new cultivars well before they become more widely available.
