Hi, fell for one of these at the Tatton RHS show and am trying to find out the hardiness of it as it's lovely (currently about 4-5 feet tall) and I don't want to lose it this winter!
Does anyone have any experience of this plant? Some websites say hardy to -7 degrees, others say take it indoors, others say as long as the roots don't freeze it's OK so I'm very confused!
Any suggestions?
Thanks!
