I bought a wine barrel (not really for wine, though) last week and let it lie around idlely because I haven't got enough potting mix for planting. But this morning I thought I could try making an "instant planting" in the barrel, using a few potted plants. This is how it turned out.
I got in there a pot of "grass" and ivy, a pot of rosemary and a pot of shrimp plant. Then I filled the empty spaces in-between the pots with plastic bags and covered on top with pine bark.
It looks natural enough, doesn't it?
