I had this plant in partial to mostly shade and it didn't do well at all. It looked awful. Someone said to move it into full sun and it has done fantastic! Love it. It does well in my heavy clay soil in zone 5b. It has multiplied in the year it's been in it's new place.

The color of this plant is more stunning. I love this plant but it doesn't like being moved. I thought I had killed it after moving it it. It looked as if it was dead for a long time but it did come back. I have it planted in full sun.

I bought 2 of these last summer and planted them in 2 different locations, one full sun and the other part sun. A month later they both started to lose foliage and by late summer both plants appeared to be dead. I left them alone and am hoping they somehow revive this spring but so far I haven't seen any new growth. I have 5 other types of euphorbia that are doing fine. Zone 6a.
Update spring 2012:
Bought two more of these early last year and planted them. They survived the winter and snow this time and are blooming now in early May. Perhaps the trick was planting them earlier in the season than I had done before. Although they are still rather small they are so cute with the burgundy colored foliage and bright yellow "flowers" that I changed my rating from neutral to positive.

I planted 6 of the Cushion spurge in my front garden last fall. They came up and were beautiful this spring. I enjoyed the leaf color and the yellow blooms. A couple of weeks ago the plants just started dieing off for no discernible reason. They grew quite nicely all summer and just started dieing, one after the other. Not sure what is going on. I would definately note a postitive experience if I weren't losing all of them. They are not going all at one time, they are defiinatley going just one at a time. Any suggestions?
