ï¿½Oh Happy Dayï¿½ is a cross between a very blight-resistant North American variety and a tasty French Marmande type. In T&M trials, ï¿½Oh Happy Dayï¿½ resisted blight infection for three weeks longer than ï¿½Mountain Magicï¿½! Clusters of 3-7 tomatoes, each weighing approx. 150g have a fabulous balance of sweetness and acidity. Grow as a cordon outdoors and best ï¿½stoppedï¿½ after 5 trusses. Excellent resistance to both early and late blight.
