Martin,
I'm very interested in helping the person who sent these trees to me find out why they lost their variegation and find out if it can be reversed. Once these trees are big enough to take cuttings from, etc., I'll try the few things that were recommended and perhaps I'll (we'll) learn something new. Perhaps not, but it will be a few months before I can act.
As far as keeping the trees if they never show variegation again -- I certainly will. I'm more interested in the quality of the figs then in the appearance of the trees when it comes down to allocating space for a new variety. Unless the figs are bland or don't perform well I'll add these unknowns to my others. Who knows -- maybe they'll be a new and excellent fig.
If it turns out they are Jolly Tigers then that's just fine with me as I've read the figs on the JT are quite tasty. If it turns out they are something new then hopefully they'll be worth keeping.
Do you think the figs produced by the Jolly Tiger are of a quality that warrants keeping that variety even if it looses variegation or is the reason for keeping Jolly Tiger mainly the oddity of variegation?
I'm hoping to get the contact info for the person who has the still variegated tree the mother of my trees (still variegated) came from and that should shed some light on the ID.
Thanks,
MGG
