Ahhhh what a beaut. I bought this plant from a specialist in Scotland who actually propagated this plant. Elizabeth MacGregor Nurseries. But sadly it only lasted a year. Stunning thou. I thought it was called 'Wild Swan' looks the same.
Thank you @brighton I must say that I've never seen it at any of my local garden centres/nurseries. We do have a Wyevale actually quite near me. I'll check it out when we're out of the monsoon season. 😂
