Xeriscaping and xerogardening refers to landscaping and gardening in ways that reduce or eliminate the need for supplemental water from irrigation. It is promoted in regions that do not have easily accessible, plentiful, or reliable supplies of freshwater, and is gaining acceptance in other areas as climate patterns shift. Xeriscaping also includes drought tolerant and sustainable plants and even may include edible plants and gardens. The Hale Kuleana Program strives to create minimal landscaping, at the same time creating natural beauty. Also, drought tolerant trees placed strategically around a home creates sun shade and is a powerful passive feature.
In Hawaii where both electrical and water are precious resources and connected, incorporating these concepts will only serve to lower overall utility costs! Please also keep in mind, it takes electricity to run water pump systems!
The following describes a list of potential drought tolerant plants for consideration;
Asparagus ferns, Blue Plumbago, Dracaena Marginata Tri, Ilima papa, Large Orange Bromeliad, Naio Papa, Naupaka, Pikake, Small Bromeliad, Spider Lily, Swan Neck Agave, and Tradescantia.
