Also, I have found that a lot of the MDB's do not like the heat here. I have a lot planted and they seem to do o.k. but some just diminish and go away. So, when I got more I put them in pots and lined them up in an old wheelbarrow and trundle them around in dappled shade depending on the heat. MDB's do NOT like being disturbed and often will not bloom the first year after planting so this is a good way to enjoy the little ones and give them the care they need. A young iris friend refers to this wheelbarrow as my 'iris mobile home'. Some are so small that the bloom could go unnoticed in early spring if there were any fall leaves left on the beds.
