Zoia said: I've been putting in regular ground over ones as I wanted a variegated carpet between the stones on the path in Upper Garden. Do the Hylos come in low ground hugging format?
Hylotelephium do have a few more low-growing species (The sunsparklers, especially). This is the best one fitting your needs (Hylotelehpium): Sunsparkler Lime Twister.
Sedum (Hylotelephium SunSparkler® Lime Twister)
Hylotelephium will bloom nearly every year, so will brighten up the area a lot. Most are upright, bushy forms. Sunsparkler tend to stay more low.
But hearing where you want them I'd reccomend Phedimus. I think spurius 'Tricolor' would do ok, but seeing where you are (zone 6a) it might die back to nubs every winter, so it would be interesting to experiment with it. Phedimus kamtschaticus 'Variegatum' is probably the best choice, it is more hardy. Out of the kams, Phedimus kamtschaticus Atlantis™ is my favorite one.
Sedum lineare 'variegatum' will also work, but is a little more prostrate.
I hope this helps ! ! !
