All the Guem or Geum they had was over 2 feet tall... would not work. Will continue to look.
No luck on flowers or foliage but I spent quite a while browsing.
Can't find the post on the picture frame planters but here is what they look like without plants at $125.00 don't think I will be buying any.
They looked like a box (sorta the old coke box) with a hinged lid on the top. The dividers were about 4" square with some sort of cushion
or water holder at the bottom.
