These plants are a bit special. Your chosen 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! Tomatoberry is a real gem - it produces long vines of sweet tangy and very juicy bite sized tomatoes with tender skins.
