Some other element was holding things back from being visually pleasing only I wasn't quite able to put my trowel on what it was.
Even slightly tattered, I'm a lot happier with this new clear view of the other plants in play minus the overhanging white stripes. This planter should stay off the Must-Be-Done list for a long long while. And after taking out the opuntia, that's twice in one month that a little subtraction has been the best addition to make to my spaces. It is probably premature to state "lesson, learned!", but I think I'm getting there.
