that's awesome that you're going to taiwan! i've never been before but i'm very interested in the native ficus. for example,
here's a climbing ficus with big orange fruit. evidently it's used to make a refreshing jelly. i'm guessing it's ficus aurantiaca, which is closely related to ficus pumila, which has been crossed with ficus carica. so maybe carica and aurantiaca can be crossed?
i searched through
the checklist of ficus in china and found 17 species that are native to taiwan and might be compatible with carica...
Ficus ampelos
Ficus aurantiaca
Ficus cumingii
Ficus erecta
Ficus esquiroliana
Ficus formosana
Ficus heteropleura
Ficus irisana
Ficus pedunculosa
Ficus pumila
Ficus ruficaulis
Ficus sarmentosa
Ficus tannoensis
Ficus tinctoria
Ficus trichocarpa
Ficus vaccinioides
Ficus virgata
over a month ago i grafted erecta, formosana, tannoensis, and vaccinioides onto carica and they are starting to grow. if they manage to fruit i will try crossing them with carica.
in japan erecta has already been crossed with carica in order to create a rootstock that is resistant to ceratocystis canker.
last november i went to costa rica for the 1st time. a bird pooped on my shirt. when i got back, inspired by the movie castaway on the moon, i scraped the poop into a pot. interestingly a ficus seedling popped up. guessing it's ficus insipida. sadly i doubt it's compatible with carica.
i'd love to know why it seems like most of carica's closest relatives are to the east of it. carica is from the east? or the birds that ate its fruit mainly flew to the east?
in any case, i'm pretty sure that my appreciation of ficus made my trip to costa rica that much more enjoyable. well, i also appreciate tropical fruit and epiphytes, so i ended up hiking slower than a sloth... man man zou.
