‘Augusta’ citrangequat is a three-way cross involving a citrange (Poncirus trifoliata x Citrus sinensis) and a kumquat (Fortunella spp.). The orange –red fruit start out sour and can be used a lime substitute but become sweet by winter with and edible sweet peel like a kumquat. The fruit are useful for marmalade, sauces, juice and fresh eating. The tree I has a dense canopy with fewer thorns making it a better landscape tree than other citrangequats. Hardy to zone 8 at least.
