As long as it does not get exposed to any late frost then yes.
And that is the thing - it will not take a frost. So at the end of the season, you'll have to dig it up and bring it back indoors.
Was it one of Lidls £1.99 specials? I bought one too (at that price you have too), but they're quite small and it probably will not give much of a display this year. So mine will be indoors until the balmy nights of summer arrive.
