Here is an O. japonica that I purchased from Perennial Obsessions a few weeks ago. It seems to have settle right in. I think it is one that I will have to put slug bait out in the winter/spring. I have a feeling the slugs would eat this one, like they did my spinosa.
I bought this plant from Shoal Creek Succulents as Orostachys spinosum. when I viewed the photo on their website I could tell it wasn't spinosum. It flowered with no offsets and I tried to collect seed but had no luck. I believe it was O. japonica. What a lovely plant. Japonica is hard to come by.
