Paul, your garden is just beautiful!
I bought two from Keppel, one is a mini one. Then I was given about 30, from two different people, mostly TB's but a few "space agers" I guess they are called - I think they are medians. ( I am not as 'up' on the iris vocabulary as I should be). All are planted, but I still need to come up with some rocks to stick on top of them for the winter. Most have rocks on them, but not all yet. I have on occasion lost some due to heaving, and my iris are all in new beds, so I want to make sure they all get 'rocked'. Later this fall I will mulch them also.
I took a bunch of mine (left over from moving to new beds) up to our family cottage in western PA just last weekend. Very late in the season up there. They all have rocks on them, and are now on their own, It will be interesting to see what survives or not.
