my favourite recipe:

fry a few Spanish onions in olive oil, until clear (sweet)

add sliced mushrooms, sweet potatoe new leaves (these are the purple shoots)

and some grapefruit juice, put a lid on the pan and turn the heat down.

serve hot when steamed (5-10 min)



as for forage - it all boils down to whether the sweet potatoe leaf has
inbuilt 

toxins as do many greens,

we don't eat it much as a salad green because i haven't checked this out,

maybe someone on the list knows.

<DIV>why waste sweet potatoe leaves as forage Dan?
we eat them year round 

here - it is far more satisfying than beans and peas,
the chickens and snails 

usually let it alone when the chickens escape.
i never dig it up unless it 

gets in the way of other plants.
i have white, pink and purple varieties, 

they are easy to grow from the
stock in
fruit and vegetable shops.
my 

favourite recipe:
fry a few Spanish onions in olive oil, until clear 

(sweet)
add sliced mushrooms, sweet potatoe new leaves (these are the purple 

shoots)
and some grapefruit juice, put a lid on the pan and turn the heat 

down.
serve hot when steamed (5-10 min)<<

Since this is a permaculture list and I have already indicated that I grow
sweet potatoes in the inner zones, partly for garden development, it seems
obvious that "wasting" the greens is not the issue.  I don't grow my greens in
zones 3 and 4.  I KNOW I can eat them, and no, there are no significant toxins
unless the plants are grown in toxic soil.  The vines are excellent stock
feed, I already know this, also, and, at harvest of the tubers,  worth
carrying to a rabbit cage, also in zone I but no out to zone 4 where the steer
is roughing it.  He eats a lot of things I could eat, not the least of which
are the local maypop vine, the only non-toxic Passiflora leaf I know of.
(Most have cyanide in them)  

Sweet potato recommends itself, as I have already written, because it
tolerates wet (and yet is very drought resistant--perfect to our sand, subject
to flooding), grows rapidly, and, I HOPE, can withstand sever grazing (it WILL
be grazed selectively) by resprouting from storage roots.  Thats the part I
don't know about, plus I don't know what trampeling by hooves will do.  I've
not tried to grow the vines with grass and weeds--I'm hoping it will smother
some bad weeds, another area I don't know about.  With about 1/4 of the
pasture under water at the moment (eventually to be taken out of pasture and
put into chinampas, but that is a slow process), I'm looking at its cousin,
the water spinach.  The state of Florida has made water spinach an illegal
plant, so OF COURSE I would not consider it, but maybe sweet potato.  Do the
vines float like water spinach?  Can anyone tell the difference?  I'm also
considering watercress for this section of pasture until I get around to
cultivating it (maybe 10 years).  Yes, I also know that people can eat
watercress.  I've seen gattle standing in water (well more like dilute sewage)
in Mexico eating the lushest watercress you can imagine, so I know this can
work.  IN this case, I can re-infect the pasture from wet areas outside the
stock fence.  Watercress appeals because it grows in cool weather and we have
a serious shortage of cool weather forage crops in the mix that has survived
15 years of abusive pasture mismanagement before we got the place.  There is a
short aquatic grass that seems palatable to the steer, but it grows slowly.
We have higher areas (and some ares now under water--this is supposed to be
the dry season) interplanted with winter rye (grain, not grass) which does
very well indeed in cool weather and will improve the tilth of the soil,
adding much organic matter in the root mass.  Yes, I know that people eat rye.
Buckweat would be another good crop for us because of its rapid biomass
accumulation, but try to get the local feed stores to order it.  They spend
hours trying to tell us we want something we don't want instead of just
writing down the order.  This is the first time I've experienced people not
believing I know what I want.  Of course buckwheat would be a once over
browse.  I'd probably let it go past prime so that it was forming seeds and
let the chickens work it instead of the steer.  Yes I know that buckwheat
seeds and leaves are good to eat.  

Let's assume that this is a permaculture list and people know that we have
zone 1 and 2 food production well under development and that issues about work
in the outer zones do not mean that we are ignoring production, and
utilization thereof, in the inner zones.  Particularly when that was stated in
the post!
