This is a garden plant that i also lost the label for lol.
Bulbine frutescens is my guess.
I'm with carol23.
I third the asphodeline lutea id from carol.
It's related to bulbine- but the bulbine is from africa and probably not a perennial in the UK- where the AL would be.
Thank you very much all for your help,i do beleive it is infact as carol states.The plant has to be mulched in winter over here and grown on very free draining soil.
