I would like to find a site that has a list of tip-bearing apple varieties. It does not have to be comprehensive. Many sites talk about them and mention only a couple.
A search of the North American Fruit Explorers discussion group refers to a list from the USDA Agricultural Information Service which has since been removed from their website. I found an extensive list of tip-bearing and partial tip-bearing apples from Royal Oak Farm Orchard. The list was prepared by Ted Swensen of the Home Orchard Society.
According to Michael Phillips, author of The Apple Grower (Chelsea Green, 2005), most apples are spur-bearing or a combination of spur- and tip-bearing; only about 1% of all varieties are solely tip-bearers (such as Cortland and Russet).
