The taste quality of a Citrumelo all depends which variety of Citrumelo you purchase. The common and easily located Swingle Citrumelo, taste like a bitter grapefruit, with the rather strong off flavor from its Trifoliate orange parentage. The vast majority of people would say that the over all quality is quite poor. The Dunstan Citrumelo, which is NOT an easy tree to locate, taste "better", especially if you apply sugar, or an artificial sweetener. I did not go to Logee's web site to verify the tree size of Citrumelos that they are currently offering for sale, but generally plants from Logee are VERY small, many times as small as 2 inch containers. As for the taste, any regular grapefruit would have a MUCH better quality and a much better taste. - Millet (708-)
