Thanks for your comments.
This is the first year it bloomed so I'm pretty excited. I guess I should give it some fertilizer to encourage fruiting. It really needs to be pruned too, but I haven't figured out how yet (should I post a view of the entire tree?)
It should look really nice with fruits against the white fence background. And I can't wait to get some seeds to grow too. These are supposed to make great rootstock for increasing cold hardiness. I'm not sure if dwarfing will be imparted as well. This cultivar is only supposed to grow to 6 ft or so. I have the Meyer lemon that is blooming and a seed grown mandarin that is showing the type of buds to indicate it's ready to bloom soon.
All of my seed grown citruses (avocados and mangos, too) are due for getting repotting/uppotted to a rich mix this spring as they migrate outside for the summer, so I should see some growth spurts and hopefully some of them will transition to next growth phase.
Flying Dragon is also said to make great bonsai subject. If I prune, I guess I'll try to see if cuttings will root.
