Citrus General Discussion / Re: My Fingerlime Grove and How I grow Finger Limes.

Finger limes will hybridize and cross readily. If you have a high presence of pollinating insects, and have a number of finger limes in close vicinity to one another such as I do, expect to get varying colored fruit--a lot. If you want to keep your fruit true, you'll have to do what the song says--keep em' separated. It is for this reason also that you shouldn't keep a variety you consider to to be sub-par, or not to your liking, around. This is true of all varieties of Australian native citrus. The CSIRO has released two varieties of hybridized native lime. These are the red centre lime (also known as blood lime, which a mandarin fingerlime x) and the Australian sunrise Lime (this is a calomondin fingerlime x). Neither are particularly good by my estimations, others will disagree.The CSIRO has also developed a cultivated variety of the desert lime (Citrus glauca). In reality, finger limes could be crossed with any citrus.
For the cross-polination, I thought he results of cross-pollination only showed up in the fruit from a tree grown from a cross-pollinated seed. Do finger lime fruit on the same tree vary in color based on the pollinator or am I reading this wrong? I like the thought of different color fruit on the same tree, unfortunately, I don't know what type of fingerlimes are available in Hawaii or if there are any. I did ask a nursery to order me a couple if they could.
