We love December, since that’s when the grapefruits begin to rain down from our xCitroncitrus ‘Dustan’ tree at JLBG. Few individuals who come to the backyard really search for sufficient to note this fascinating plant. xCitroncitrus ‘Dunstan’ is a bigeneric hybrid between the hardy trifoliate orange, Poncirus trifoliata and a grapefruit. The result’s a winter hardy fruit that’s fairly darn shut in measurement, style, and look to a grapefruit. To be technically right, the fruit is named a Citrumelo. No matter you wish to name it, it’s fairly darn cool to be harvesting hardy citrus right here in Zone 7b. Final yr, we harvested over 3 dozen fruit off our single tree.
