I just received a small bag of Lycoris squamigera (naked ladies, resurrection lily, surprise lily, magic lily).

I have been creating beds with living mulches like sedums, ice plants, & thyme. I have heard these lilies are pretty stout. Would they be stout enough to force their way up through sedum tiles? If not, any of the others above?

Magic lilies have a lot of spring foliage which disappears in summer; scapes pop up around Aug. 1st (here) all by themselves. I don't know about through a heavy bed of ground cover sedum. I believe the scapes might have but little problem, I don't know about the spring leaves though.

I should say btw, that the sedum tiles have had the coir layer removed prior to planting...so just sedums & soil.

I have never grown them, but if you can make some holes in the sedum cover, it might be worth a try?
