In CA, I just tied or glued them to boards and hung them on the lanai patio. And, of course, they could stay outdoors year around. I did the same ... doused them with the hose occasionally. In LaJolla, the fog rolled in many days at least for a little while so didn't have to think much about watering. I loved being able to have them outside like that as opposed to indoors. Of course, I was zone 10 and 11 out there as you are. The problem here is that there is little selection. You can't find them here most of the year.
