Global Vegetable Seed Expertise



Tozer Seeds have been breeding lettuce for over 50 years and were among the first to introduce mildew resistance. We continue to work hard to introduce more resistant varieties but also concentrate on enhanced texture, flavour, shape and colour. This attitude to breeding has led to the introduction of internationally grown varieties such as Ashbrook and Osterley and the launch of our latest outstanding babyleaf variety TZ 7192.
