Comments regarding Big Tree Peony

I ordered several tree peonies (rockii, suffruticosa, ostii) and seed. Communication was a little spotty - sometimes replies were same-day, sometimes a week later - and it took a full month after payment to ship. Transit itself was rather quick (a week?). The plants look good - two are only one root and one stem, which is a bit smaller than expected, but most had multiple eyes and one or two were large enough to divide before planting.
I am concerned about what the other commenters say about plants not being true to type (plants were ordered this fall, and won't bloom for a couple months, if not a year for the smaller plants), but overall it has been a positive experience.
On the web as both Peaoniarockkii.com and china- plants.com.

I have ordered Japanese, Chinese, Rockii, and Herbaceous Peonies from Zhongchuan Nursery several times and have been very happy with the plants I received. They offer replacements for any that are mislabeled. The tubers are large and healthy, and everything is packaged professionally. The sales expert I have dealt with is Irene. Her communication skills are excellent, and she is very helpful with the ordering process. I highly recommend this nursery.
