You'll like the Mono, I have several, They tend to have a spreading habit, instead of try to grow straight up, and lend themselves well to cascade style. pretty pinkish-kinda purple flowers, more pinkish. Mine bloom heavy in the spring and sporadically throughout the year, sometimes even in the winter. I don't know if WV had it in a greenhouse or not, if he did, I would protect it from the cold. Mine have been on the bench all winter and have seen temps down to 30. Frost is OK, if it freezes though, usually the only thing that gets zapped will be the young tender growth.
You could just put it outside when it is nice, and bring it in when you expect a cold spell. I had a book that translated the Japanese names to English and if I remember correctly, Momo no Haru means "Spring of Peaches"
