http://www.annalsnyas.org/cgi/content/abstract/870/1/265 As to the
seeds.They are out there,but hard to find.I lucked out& someone traded me 30 different kinds.I grew 2 last year.I bought A start of asao clemtris.for now its with a pink
rose on arbor still dormant I guess.Alot of JMG are short vines& great for hanging baskets.some have large
flowers.a few are scented& alot have leaf variegations and are in different shapes.Sydney will stay open almost all day.
Michael that is not the smallest.My early call& german blue have smaller
flowers.I loved the speckles& will now have to grow my 4 flaked JMG.The early calls don't stay open long,but are in morning sun& get blasted once suns up over the
trees bout 9:30ish.You'd LOVE
growing these.
This one hangs on my porch deck.
the center is white by end of day.This was took about 1ish.I stay real busy in the mornings(watering,feeding dogs,ducks,hand pollinateing)I love the pink edgeing.
This is robe
Its a pink with a blened type look.I've just GOT to learn to juggle my tea,a hose,camera& phone huh.looks good at 6 amish..lol
And this is pretty also& stays open longer.It was marked as pink& is the 1st
flower.
And sydney.I like it.I have it rigged up on my hanging contraption.no one sees it but me,the deer& anyone I bring about back to have a look see.You can see it some from the bathroom but the etcheing on the glass blocks alot of that.
I'll leave ya'll drooooooling
