Citrus x citrofortunella
Conestoga House & Gardens, 1608 Marietta Avenue, Lancaster PA
Several specimens of this beautiful dwarf reside in the orangery and elsewhere at Conestoga House. Able only to withstand temperatures down to 20 degrees F, this tree is widely grown in the Philippines, but in America it makes an excellent container tree: shiny dark evergreen foliage; fragrant, self-pollinating white flowers; and abundant tangerine-like fruit. Planted in the ground in a warm climate, the tree only reaches 4-6 feet.
This amazing species is especially attractive while decorated by its small tart fruit which is excellent for flavoring foods and beverages.
