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.

Cultivared sweet peas

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.
