Eustis Limequat

Eustis is a Key lime × round kumquat hybrid from Walter T. Swingle’s limequat breeding work in Florida. The 1923 account identifies it as CPB 48798 and describes light-yellow, oval to nearly spherical fruit with a thin edible rind, tender juicy pulp, and a sharply acidic, lime-like flavor. The tree is described as evergreen and vigorous, with small spines on bearing twigs and successive crops. Published accounts place its cold tolerance between Key lime and kumquat; individual protected-tree reports do not establish an unprotected survival limit.^⁠[5]⁠[1]
