Terry:
I should have read your second post before I responded to your first, don't know if I offered anything helpful. I correspond with a fellow in Australia that grows Finger Limes commercially. As a commercial crop they are just starting to "catch on" there. Over time I've learned a bit about them and I think I've finally figured out how to germinate the seeds, with decent sucess. There is disagreement, among growers, as to whether or not seeds from a specific cultivar will produce the desired color (of fruit). There are four (4) primary, recognized colors: red, yellow, green and purple/black. Some say there is variability within the same tree. Since it will be a while till I can pick a fruit crop I'll just prefer to believe that they will come true from seed. I do have a 3 gallon "green" F. Lime. Currently, I am growing "sanguinea" (red) from seed. Budwood from a "proven" tree would be the first/best bet. I'd say that the taste is to be "acquired"...they kinda taste like turpentine to me! Good luck.
