Bit, I sell far more Plumeria cuttings/rooted cuttings to non-tropical area people than to those in zones 10-11. Probably 10-1 ratio. I live in an anything-but-tropical region, and grow them successfully. Plumeria simply need different care (think dormancy) for us in non-tropical areas. Now, you might be able to grow them inside a house, but I doubt you will ever see them bloom. They are trees in the tropics and need full sunlight to bloom and be vigorous growers. I send "care" instructions with every one I ship out so you know what to do with the plants when you get them. I also describe the "dormancy" part of growing them on my website, www.tropicalplantsandmore.com. Ken
