An unusual plant is flourishing in the greenhouse - which I built 6-8 years ago as a winter home for a calamondin (miniature orange) I've had for over four decades. Daughter planted one of its seeds and it grew slowly for several years until this summer - when it sprouted 3+' in one season.
A key lime also winters in the GH. Well, it seems that these two go together and my daughter just happened to plant one of its progeny. (My grandaughter loves those thnigs.) The key lime parent has little thorns/spines, but this new hybrid has freakin' harpoons. Spikes 2-3" long! Talk about hybrid vigor....
Now the Wiki entry for calamondin also calls it a "golden lime" so I can see why they might get it on botanically - so to speak. Since both the calamondin and the lime are rather prolific WRT fruit set, this hybrid might do the same. I'm wondering how to prune this oddity.
