Native plant outlets may have an assortment of interesting Hawaiian beach plants that would grow at your new place. There is an entire special and badly diminished local flora that is not well represented in Hawaiian gardens. Most landscaping features the same universal favorites planted throughout the tropics.

Ask your neighbors once you get there what grows best for them and they will probably give you cuttings and starts. Bouganvilla, cactus, dragon fruit, aloe, kiawe (mesquite), plumeria are all probably good choices.

A lot of folks have drip irrigation lines in that area. Will your water be catchment? If so, then xeriscape landscaping might be something to look into to save water.

The Amy Greenwell botanical gardens near Kona has some native Hawaiian plants you can buy and they can probably advise you on some dry landscaping. Ohia trees are growing through the lava in that area so you could add more of what's already growing.

Good luck, as a suggestion, please visit and stay for min of 6 months first before pulling up stakes on the mainland. Then decide if you want to move. Things are soooo different here, especially to where you are going, it's best to check it out first.
