Linda, your useful information and propositions concerning iceplant have really got me going on a little rant here!
Iceplant is barely edible to me, definitely not a 'good edible permaculture plant'. Our grandparents may have found iceplant quite useful, but many of them were not aware of the value of native plants in thier ethnobotanical and wildlife habitat functions, as many of us are still not aware of today.
Wow! With all the useful, uniquely native, and other relatively non-invasive plants to promote, are we entertaining the idea of planting something that we all have all observed spreading locally and creating huge monocultures, even taking over some relatively stable native coastal plant communities? OK, it may be a very interesting and useful plant, but it doesn't mean we have to plant it, to use it- Don't we have enough of it to use already? From my perspective, planting iceplant would be a lazy choice. For others, do the cost/benefit analysis and compare to other plant options (and combinations) to see what your best choices might be.
from the website you linked to (http://www.plantzafrica.com/plantcd/carpobed.htm):
Conservation status
Carpobrotus edulis is not regarded as threatened in its native habitat, but it is invading natural areas in other parts of the world and threatening the survival of other species. In California, where it has been used since the early 1900s to stabilize the soil along railway tracks and roadsides and as a garden ornamental, it has naturalized and is invading coastal vegetation from north of Eureka to Rosarita Bay. It is known as the highway ice plant in the USA.
from another source:
There is evidence that iceplant also competes indirectly with native species. It has been reported that iceplant can lower soil pH and also affect the root morphology of some native shrubs (D'Antonio, 1990a; D'Antonio and Mahall, 1991). It is also possible, because iceplant does not seem to be palatable to most native herbivores, that its presence could increase browsing pressure on native flora and influence the species composition of herbivorous fauna. (3) Invasion by the alien succulent, C. edulis , has become a common occurrence after fire in maritime chaparral

I am definitely not suggesting that I only use natives in my plantings, but come on! Let's be a little more creative than planting something that can actually lower bio-diversity, like ice plant does!
Now having gotten all that out, Thank you for all the useful information on iceplant, as I am actually quite interested in the many uses of locally invasive (well adapted), or overly planted, seemingly useless landscape plants, (such as Agapanthus, or the various shrubs known as Broom). Considering all the qualities that were noted, perhaps it's economic values can be used as an incentive to harvest and remove it, to fund replacement with a more diverse, locally unique, and productive assembly of plants. If the plant selection criteria is to have some fire resistant, good tasting fruit and medicinal uses, how about some diversity plantings, starting with native prickly pear and some Aloe spp., Agave spp., and so many others. . .? Rather than more of the same old-monoculture, lets plan for more diversity and complexity of relationships!
be fruitful-

Subject: [Scpg] is ice plant a good edible permaculture plant?
Iceplant (Carpobrotus edulis aka Hottentot Fig) has a bad
reputation in California these days, although its usefulness was much
valued by our grandparents' generation. It's an
attractive, low-growing groundcover plant now considered invasive and
governments are spending a lot of money ripping it out and replacing it
with native plants.
But perhaps from a permaculture point of view it's worth another look? It's
an amazing plant that performs multiple useful functions.
Yields an edible fruit which has been eaten by humans
since archeological times. Fruit is fleshy, 35 mm in diameter, shaped
like a spinning top, on a winged stalk, becoming yellow and fragrant when
ripe. The outer wall of the fruit becomes yellowish, wrinkled and leathery
with age. The seeds are embedded in the sticky, sweet, jelly-like mucilage.
The fruits can be eaten fresh and they have a strong, astringent, salty, sour
taste. They are not as tasty as those of C.
acinaciformis (purple iceplant, can be used to make delicious jam)
and C. deliciosus (purple or pink iceplant) which are sweeter. See http://www.plantzafrica.com/plantcd/carpobed.htm
Edible by some wildlife as well. Flowers draw bees and
are also eaten by animals. In S. Africa, leaves are eaten by tortoises.
Holds water and thus is an effective fire-resistant
barrier around house or in foothills in fire-prone areas.
Drought tolerant
A coastal plant
Low maintenance. Vigorous and will grow where little
else wants to grow
Wind resistant
Controls erosion by binding hillsides, stabilizing
sandy dunes.
Shallow-rooting so good for roof gardens
Like most succulents, a useful "living mulch"
groundcover.
"Can be planted on flat, sandy ground, on loose sand dunes, gravelly
gardens, lime-rich and brackish soils as well as in containers, rockeries,
embankments and will cascade over terrace walls."
Pretty yellow flowers and attractive rusty coloration
even when not in bloom (you can see its autumnal-toned beauty in many
paintings of coastal California scenes).
Has medicinal uses and is a first-aid plant. "The leaf
juice is astringent and mildly antiseptic. It is mixed with water and
swallowed to treat diarrhea, dysentery and stomach cramps, and is used as a
gargle to relieve laryngitis, sore throat and mouth infections. Chewing a leaf
tip and swallowing the juice is enough to ease a sore throat. Leaf juice or a
crushed leaf is a famous soothing cure for blue-bottle stings - being a
coastal plant it is luckily often on hand in times of such emergencies. The
leaf juice is used as a soothing lotion for burns, bruises, scrapes, cuts,
grazes and sunburn, ringworm, eczema, dermatitis, sunburn, herpes, nappy rash,
thrush, cold sores, cracked lips, chafing, skin conditions and allergies...The
leaf juice also relieves the itch from mosquito, tick and spider bites both
for people and their animal companions. In the Eastern Cape of South
africa it is also used to treat diabetes and diptheria."
So what do you think? It is worth another look? Could this be a
useful plant for various garden and permaculture designs? Or should it be
shunned as uncontrollable?
Linda

Dear friends,
As a friend and supporter of Van Jones and progressive government, hearing
of his resignation from the White House - I am sad today, again, at the
state of our country, and yet so inspired by Van Jones' courage, and happy
and proud that he is part of our movement for healing the planet and human
communities. Below is what I found of his resignation statement, and a few
links that help get to the story.

>From Van Jones' resignation statement:
I am resigning my post at the Council on Environmental Quality, effective
today. On the eve of historic fights for health care and clean energy,
opponents of reform have mounted a vicious smear campaign against me. They
are using lies and distortions to distract and divide. I have been
inundated with calls - from across the political spectrum - urging me to
"stay and fight." But I came here to fight for others, not for myself. I
cannot in good conscience ask my colleagues to expend precious time and
energy defending or explaining my past. We need all hands on deck, fighting
for the future. It has been a great honor to serve my country and my
President in this capacity. I thank everyone who has offered support and
encouragement. I am proud to have been able to make a contribution to the
clean energy future. I will continue to do so, in the months and years
ahead.
