Hello, I've got the white variety of Crinum x powellii growing in the border of my garden. Has been there since we moved in in 2008 and since then has probably only flowered twice. I threatened it at the beginning of the year, that if it did nothing this year I'd dig it up and it would be but in a pot.
Came back off holiday and guess what?! Yes, it's flowered. One stem with about 8 flowers on it.
Any ideas why it's took so long to flower and when would be best to move it?
