i HIGHLY suggest Akebia quintata; although, you should, if you want it to
fruit in the time allowance you mentioned, buy a gallon pot and enquire
whether it is at least 3 years old. but they twine so beautifully and they
have beautiful maroon coloured flowers and then they bear very tasty
fruit--somewhat between (imho) a passion fruit and a custard fruit---VERY
seedy, but the flesh part is VERY tasty!!!!!

just one suggestion: if you live in an area with squirvels (yah, i know how
to spell them, but it's SO TEMPTING to squirvel them!!)....you MUST cover
the blossoms with bird netting or that 'floating crop cover' stuff....or
even just plain bedroom sheets....gently, so as not to bruise the blossoms,
otherwise the squirrels will eat every blossom and then you'll have no
fruit. ;o(

have fun with them....their trellising habits are such fun to watch!!!!

p.s. i live in usda zone NH4a and have been told by the local nursery they
won't survive the winters here, but so far they've survived every winter for
the last 8 years, including two where it went down to -30 for three weeks!!
AND the one which blossomed (and consequently got munched on by the
SQUIRVELS (that word in MY secret garden language means: DAMNED SQUIRRELS)
anyway....that one lives on the north side and seems MUCH happier than any
of the others i have around the garden.

oh, one more thing----bugs don't like them: i have one on a trellis with a
grape vine and every year, the rose chafers, the japanese beetles, and the
tent catepillars munch the poor grape vine to the point of defoliation---but
they never even take a nibble from the akebia!!! you should google it and
see the pretty blossoms and five-pointed leaves!!

exotic vining fruits?

I am really limited to things that will grow in a year, because we will
probably only be in this house this year and next year. As such,
grapes are probably out. However, I would be interested in any sort of
vining fruit that would do well on a trellis. Thanks!
