“Mini” Hydrangea? Can I keep it in a pot? – Reddit Post

I bought this beautiful hydrangea plant last February, it was marketed as a mini hydrangea, which I’m unsure is an actual cultivar. I’ve never had a hydrangea and thought I had killed it over winter- it was all sticks. Well, now it’s spring and it’s pushing out more flowers than leaves! It originally came in a 4” pot, now in a 6”. I’m wondering if anyone recognizes this cultivar or has advice on its longevity in a 6” pot. I can certainly size up the pot, but unfortunately I can’t plant it in the ground on this property. Thank you!
