I received Siloam Peony Display in May of 2014 and it bloomed for the first time for me last year. The flowers are very pretty but they have yet to reach their registered size of 6 inches. Most of mine this year are 5 inches but they do appear to be larger than the ones last year.
SPD blooms mid-late for me. So far this year every flower has been perfect! I have other doubles that occasionally throw out single flowers but that is very rare for SPD.
It hasn't increased well for me but considering our drought last year (and my lack of watering) I wasn't expecting it to. I'm hopeful that with all the rain this year SPD will finally start clumping up.
A very nice daylily for the front of the border due to the short scapes.
