The Thompson Pink Grapefruit originated in 1913 as a pink-fleshed sport of the Marsh White Grapefruit. It is also called Pink Marsh and was first propagated by Royal Palm Nursery in Oneco, Florida in 1924. It is seedless as Marsh White and has the same appearance inside and outside of the fruit. It matures earlier than Marsh White, from October through February but can hold its fruit on the tree for many months. It has a high yield and the tree will grow to 25 feet.
