I used to grow aerial potatoes quite a few years ago but didn't really like the taste compared to the Chinese/Winged yam, another Discorea species. It was also very weedy, not as bad as the Madeira Vine mentioned but it still dropped very large numbers of small bulbils that then wound tightly up plants and smothered them (similar to what Wikipedia reported in Florida, where the vines grow to 70 feet long). It became quite a nuisance because it was also hard to pull out. The aerial potatoes are impressive and can weigh up to a kg each. The leaves are dinner-plate size and attractive. Green Harvest doesn't offer them for sale because of the weediness, I believe this plant has serious weed potential if it gets into rainforest gullies. Taste is a very individual thing, I found them a bit soapy. Also I was concerned about botanical reports that they were not truly edible and contained possible steroids. One species of Discorea is grown in Mexico to produce the hormone drugs used for contraception. If you are keen to grow some they should be fairly easy to come by.
They are not related to Madeira Vine which is actually a distant relative of Ceylon Spinach.
Wow, that's huge! I thought they must be similar size to the air tubes on madeira vine, but obviously not...
I have enough weeds in my yard and have just discovered that I've introduced a new one 'Fat Hen' *doh*
That's what I thought but Larissa posted this on my page, so not so sure - I'll have to do some research myself when I get time.
Donna - is this what you have? Its on the weed list. http://www.weeds.org.au/cgi-bin/weedident.cgi?tpl=plant.tpl&sta...
No sure what that means though.
Fat Hen is a weed but also edible, it ia a close relative botanically of Good King Henry (also called 'Wild Spinach' in the UK), another Chenopodium species. The name says it all, Fat Hen is a great poultry forage or 'throwever green'. I harvest these weeds young for the chooks and try to avoid having them go to the seed in the garden. Weeds can be surprisingly nutritious, we do a wild harvest for a weed pesto. Purslane figures prominently but young fresh Fat Hen or Chickweed is good too.
