I urge you NOT to use ice plant - there are other plants much better suited to your needs. Here's some information about the problems it causes, and some good substitutes, from an article in the monthly newsletter of the San Diego Horticultural Society:

Years ago, Freeway iceplant (Carpobrotus edulis) was touted as the perfect solution for fire safety. Planted on hillsides of thousands of homes in San Diego, it has since crawled off the original site and into neighboring Open Space parks, endangering unique plants by smothering them. Iceplant provides little habitat value compared to the plant community that it is replacing because it has very shallow roots that do not hold soil well. Close inspection often reveals gullies underneath the twisted mat of vines. After rain iceplant engorges with water, substantially increasing its weight. As a result iceplant can cause the deterioration of steep hillsides by encouraging slumping  potentially endangering the house above.

What can I plant instead? There are many non-invasive groundcovers that are readily available. Here are a few: Wall Germander (Teucrium chamaedrys, T. lucidrys), San Diego marsh elder (Iva hayesiana), Ivy Geranium (Pelargonium peltatum), Elija Blue Fescue (Festuca cinera ÂElijaÂ), Dogbane (Plectranthus foetidus ÂLois WoodhullÂ), Wild Lilac cultivars (Ceanothus spp.), and Manzanita cultivars (Arctostaphylos spp.).
The following are also INVASIVE groundcovers very similar to Iceplant and should also be avoided: Red Apple (Aptenia cordifolia), and Crystalline Iceplant (Mesembryanthemum crystallinum).

Thanks for the response Susi. I appreciate your input greatly. I had no idea that ice plant did not hold the soil together well. I had been told the total opposite. I was mainly recommended Ice plant because of its fire retardant qualities. I will look up the plants your article recommends. Thanks again.

Just a note that there are many other plants with the common name "ice plant" that do very well in the erosion control department, namely Lampranthus spectabilis, which I've had in my yard for many years. :)

I have a white one, as well as this pink hotty. One flat of plants covered quickly, yet not invasively. But this is not your typical coastal "ice plant".

I would love some Ice plants....and yes the succulent type..with big triangle leaves. I lived in Monterey and it grew all over the place...what some people in different parts of the world think this is a junk plant, other parts like it....believe it or not... it freezes in zone 8...I would have to take starts and put them in my greenhouse for the next year......SO can anyone get me some?

I think you are looking for the non-invasive Delosperma, such as Delosperma cooperi.
