While on the one hand, it's nice to see so many people conscious of the invasive plant problem, in this case they are wrong. Calipc, The California Invasive Plant Council recommends using Delosperma cooperi instead of the ice plants which are such terrorists. Many coastal sites in my Sonoma and Marin County areas are completely taken over by them.
Check out Calipc for information about invasive plants, how to get rid of them, and what to replace them with.

I'm a botanist and conduct noxious weed surveys, and am a member of the local Native Plant Society (among other conservation groups), and am a Master Gardner. We don't need misinformation being spread, it is harmful. This is like saying all grasses are noxious weeds, extrapolated from one species of grass being a noxious weed.

Master Gardeners, NPS and Nature Conservancy volunteers have been trying to eradicate ice plant from the Channel Islands for a long time. Someone thought it would be a good plant to stablize the cliffs and wind swept areas. Wrong!!! It has decimated many of the native plants which are found only on these islands. If you live in CA don't plant in your gardens. It attracts slugs/snails and trash and kills many good plants.

I garden on sandy soil just north of Savannah, GA. I did not know of this plant until I moved here two years ago, but it is now a staple in my garden. It is THE plant that draws the most comment from visitors, despite it's small size.
In my garden, D. Cooperi is evergreen, thrives in sun in dry or damp soil (my soil is sandy, but well enriched and well drained). It forms a 2" high dense medium green mat (sorry - no foot traffic, please), and has the best color and bloom in damper areas. From early spring through fall it produces small daisy like bright magenta flowers. It spreads at a reasonable rate, but is easy to control. I have not had any seedlings appear. It is easy to propagate from cuttings at any time and seems to have no pest or disease problems. Also looks good... read more

I planted Delosperma cooperi in my yard here in southcentral Kansas last year and it did beautifully in spite of severe drought and many days of temperatures in excess of 100 degrees. It started blooming in the spring this year and has bloomed profusely every day since then. It has been a beautiful addition to my garden. Since we are once again experiencing drought conditions, I am so glad I planted it last year. Although it definitely spreads, I have found that easy to controll.

I've had this plant draping beautifully over the cedar edging and down onto the cement curbing for at least ten years. It is fantastic. This is a very hot, dry, sunny bed where Autumn Sage, Russian Sage, Purple Heart, bearded iris, Nandina, and so on thrive together happily. I was admiring the blooms the other day and noticed that the stem of this plant has grown quite big and tough. I like the way that it softens the edge of that bed so have taken a few cuttings so I can spread it around.

The Purple Ice Plant was planted by my daughter-in-law along her front sidewalk. Her house is in Independence, Kentucky. I did not have any experience with this plant until she planted three of them. They thrived and had many, big purple daisy-like flowers in the Summer of 2011 which seemed to glow in the sunlight. I love this plant! It survived the Northern Kentucky Winter and has spread out somewhat, which looks great this Spring 2012! She wants to complete the sidewalk area with two more of these, and I just found them for her. Her sidewalk area is in mostly full sun, and the Ice Plant did great. I am thinking about planting some in my perennial bed as well.

If you are looking for a beautiful groundcover for full sun areas prone to drought, this is your plant! I grow it in tough, unamended Georgia clay, and it absolutely flourishes and has spread several feet in wide in only two years. It forms a thick web of stems a few inches tall. Also, the flowers open during the day and close at night. One note is that it is not suitable for foot traffic, as it is a succulent.

This plant is actually not invasive in the CA bay area, as has been posted by some. Carpobrotus edulis is an iceplant that is highly invasive, but delosperma cooperi is recommended as a non-invasive alternative groundcover by CAL-IPC (http://www.cal-ipc.org/landscaping/dpp/pdf/SFDPPPrintable.pd...).

It looks beautiful here and grows really well and should not be confused with another 'iceplant' carpobrotus edulis.

Awesome plant that blooms continuously from Spring to Fall for me. Who cares if it's native or not? I grow many plants that aren't native to this area. There is no rule that says a plant must be native. If you think that, fine but don't try to force that view on everyone else. It's not invasive in my flower bed either. It grows where I plant it and stays inside the edge of my flower bed. It also hasn't harmed the "native" plants that grow beside it in my flower beds. Don't be so closed minded about plants. These plants can be used to prevent the spread of fires in dry areas of the country and save on watering since they contain so much water and require little water to grow. There are many other positives to them as plants as well.

Delosperma cooperi:

I have only grown this in pots and as a short-lived ground cover. In containers it creates a nice drought-tolerant cascading plant, alone or with other plants. As a ground cover it performs where elevation permits excessive precipitation to quickly drain off. Unbearable heat and humidity melts ice plant in no time especially when soil is clayey.

Colors of flowers and silvery-blue/green leaves (punctuated with little whitish-silver dots) add radiance to landscape: Ice plant reflects and scatters light well and should be used in the landscape where passersby attention needs to be garnered.

Basic care is more than sufficient--care requirement is so minimal, that if it were a higher organism such as a human, you might get reporte... read more

This seems to be the only 'Ice plant' (Aizoaceae) which is reasonably hardy and successful in British gardens. It's tolerant of wet and cold and can tolerate less than perfect drainage.

In a hot situation it grows quite fast and flowers extremely well from May to the first frosts, and the flowers can be 5 cm across. I've grown this plant for about thirty years in Southampton, but unlike the U.S., it has never been very popular in the U.K.- our sunshine levels are just not high enough. It's surprisingly rare in Cornwall (I thought it would be everywhere) but the duller, cooler summers may not be to its liking.

I have brought it inside for the winter since I was unsure if it was hardy in my area.

This plant has its positive and its negatives.

Firstly the positives are that it has beautiful flowers, creating masses of colour in summer, along with interesting foliage, and is completely hardy.

The negative side is that it grows extraordinarily fast, needs to be contained or it becomes invasive, and also like to self seed everywhere. If not checked it could take over entire areas of garden, and even escape into the wild.

Nice substitute for Lampranthus for colder areas.

I absolutely love this plant. It is very hardy and can withstand our common temperatures of over 100 degrees and since it is a succulant, it can go without water if necessary. It is a fast growing ground cover, so it is probably best planted in a confined area. I first planted a half a dozen or so starts in a large 2x15 area late last summer. The area is at least 3/4 filled in and I have transferred some plants to other planters. It looks beautiful!

Zone 6-7, elevation 2600'. Living in the Blue Ridge Mountains of WNC. A friend gave us a handful of ice plant, most with roots a little over two years ago (2004). We now have a solid patch that is about 40' X 20'. It's mid May now and I can see several flowers. Can't wait to see the whole patch in bloom this year. Great ground cover and almost no work involved. We have very little foot traffic on the plants, usually only to pull a few weeds.

They also make a nice contrast against the ice plant.


I live in Silicon Valley {California} & the plant grows quite well here. Water it every day {in the summer} after the sun goes down.

Propagation is painless.

Just cut off a piece long piece, gently take off the small leaves from the stem {about 1/2 inch} then place in good dirt. walla... you have more plants.
