I think those are still wonderful!
U. alpina may be a common plant but when grow well (like yours) it’s hard to say everyone doesn’t need one!
Do you give yours any dry rest to encourage flowering?
Just the CPs right? ‘Cause lots of my other plants have fertilizers in them which I don’t think is good.The water that drains from your plants will have all sorts of life in it. Try using it on your U. Alpina.
