Hello Rachael H,
Oleanders, to use the common name, are Mediterranean shrubs so they are a little tender. You'll see them lining the roads if you go on holiday to Spain. They require frost-free conditions, but otherwise are tolerant of a wide range of soils, and handle dry conditions well. That's why they are planted by the roads! It's always the case that plants grown in pots need more attention when it comes to watering, than those grown in the soil, but oleanders are drought-tolerant, so your plant will still do well if kept on the dry side. They don't require much feeding, which again makes them a good roadside option. If foliage is damaged by frosts, the plant can put energy into producing new foliage rather than flowering. If you have space inside it's definitely worth bringing it in for the winter, but until then it should recover slowly over the next few months.
