I was given a 'sprouted from ground' peony from parents plant last year, (had plant 40+ years , having heard they didn't like being moved i initially left it in its pot , buds came but didn't open wondered if was the horrific weather we had in summer. Spotted pot had a red shoot popping out if it today , now what to do with it ? I don't know how it will be in my heavy clay peaty soil (completely diff from parents 40min away) and a lot colder here. It's a standard one , red , do I pot it up and leave there so can look after it, be bold and plant it

The original plant was from my grandparents garden , I lost them when I was very young so has a sentimental element ...
