These plants are a bit special. Each variety has been skillfully grafted onto a modern cultivated rootstock. This gives the plant greater vigour and added disease resistance meaning you'll pick heavier crops over a longer period. The majority of commercial tomatoes are grown like this because professionals know the extra cost is more than worth it Our collection contains two plants each of Tomatoberry - a luscious plum, Tastyno - cherry tomato with exceptional taste and Vanessa, large round fruits.
