Thank you, Ursula. Deutsche kaiserin is almost finished, and I need to move it to more shade, but the rest of my Epis are full of buds. I hope they will bloom more or less together. It will be a great show.
As to the structure, it has to be sturdy, as we do have earthquakes and strong winds. All of my 4" pots, and smaller are in the spice baskets so they don't blow away.
