Ok .. in that case i would treat it as a houseplant for now , enjoy the smell indoors . once it has finished flowering and you can be sure no more cold nights and frosts[ probably early May] put it outside. The one I had as a houseplant last year is quite rampant this year and I just put it in a bigger pot outside and gave it some canes to grow on ..hope it will flower this year.
Water the plant regularly ,just letting it dry out very slightly in between [probably once maybe twice a week] ,need to keep an eye if you have a radiator underneath the windowsill as it may get a bit too warm .
