I first got this iris as a bareroot plant in November of 2017. I potted it up into a 1 gallon pot and kept it moist into spring of 2018.

In spring of 2018 (amazed that it was still alive, in part because it was getting too warm and sunny on the patio where it had been growing), I put the potted iris underneath a deciduous oak (where I already had a couple of in-ground PCIs growing). It stayed in that pot all summer and fall, with only whatever stray irrigation it might have gotten from the 2x/week sprinklers, plus a rare hit of water from a watering can. (It got some late afternoon sun in that location.)

I went out there today to look at that area (my garden helper had dug a hole there that he wasn't supposed to), and was stunned to find the plant in bloom. A PCI blooming in December?!! And it's still in its one gallon pot (which supposedly is a no-no - no PCIs in pots more than a year).

Color-wise (not to mention a nearby I. confusa), that spot is not an ideal location for this iris. But otherwise yes (another rule broken - no afternoon sun).

What an iris - it is certainly a keeper (if it survives my putting it into the ground somewhere).
