Do a search on rebloom and you'll find lots of info.

People in very cold winter zones reported early bloom being caught by late freezes and fall bloom being nipped by early frosts.

My zone is perfect but not many rebloomers catch my fancy. I planted Belvi Queen and she did not rebloom her first year which I understand is quite normal.

Rebloomers need an extra feeding after initial bloom and regular soakings during summer to rebloom.

I,m in zone 8 and I have fallen in love with the rebloomers. I have had to cut the stalks and bring them in the house because of frost threats. Also too much rain can rot the bloom if you leave them out.

I don't know if they will do well in your zone. Rebloomers like warm autumns. Some people on this forum avoid them because if they rebloom and there's a frost it can kill the plant.

I live in SoCal, so I am a huge fan of rebloomers. As a matter of fact, that is all I will plant now, because I have been spoiled by Total Recall, which blooms from April to November here. Most will not bloom like that, but I am hoping for some rebloom this fall on Frequent Flyer, Jennifer Rebecca, Alice Goodman, Beverly Sills, English Charm, and Cajun Rhythm.

I don't care for purples, but there are some purple rebloomers will bloom year-round in warm climates.
