Diggers offers more than 500 types of heirloom seed, and each year a selection of these are sown and grown in our trial gardens to ensure that they are true-to-type, and to measure how they stack up against other varieties of the same species.
Specialising in publicly-owned open-pollinated (OP) heirloom seed is not without its challenges. The cross-pollination of varieties can greatly impact the resulting seed and, while this can be an interesting experiment in your own garden, it is undesirable when trying to preserve the traits and characteristics of varieties that generations of gardeners have grown to love and trust.
