In my view, Howgate Wonder is an under-rated long-keeping cooking apple. It is also a good pollinator for Bramley. The flavour of Howgate Wonder is not outstanding. However it has so many other qualities from the reliability and disease-resistant point of view, that most people love to have this variety in their garden.
Howgate Wonder keeps for a very long time and makes wonderful sized fruit. It lacks the acidity of the Bramley, but makes up this shortcoming in many other ways. It does not need sugar added and therefore it is very suitable for diabetics. Make sure that during the summer months it does not go short of water. Most suitable variety for water retentive soils anywhere in the UK.
