We have 2 big rocks, my husband took a chisel and made some good size holes for me to plant in, we shall see how it goes.
So far I put Ivy in one and have not planted in the second one as of yet. They set under a tree so won`t get sun baked
or overly saturated in rain, as there is not perfect drainage, a fun garden art experiment anyway. Last year I put Alyussum (sp)
seeds in and they sprouted and bloomed and did well, so I might put those in the other one.
