Gardeners' Notes:


On Jun 30, 2012, Clary from Lewisburg, PA (Zone 6b) wrote:

I have downgraded this plant to a negative. It spreads so invasively that I had to remove the entire patch and a 1' periphery just to be sure. When handled the plant breaks apart and the smallest bit will root and spread. Accidentally hit it with the snow shovel and it's 1000 new plants wherever the pieces land. Although the flowers are brilliant, the plant looks brown all over once they die off. Couldn't weed whack or shear the dead flower heads for fear of spreading little bits of sedum around. It's gone now, and thank heaven none of it got into the lawn.

For eastern United States zone 4, this little guy is one of the top 5 toughest of the true sedum family - they shrug off the rains, winter snow cover, etc.

Lovely little filler plant - great for front of a border. I've found babies of it up to a foot away that are easily moved. Good manners, non-invasive. Ours is in half sun all day.
