This family-friendly and admission-free event is focused on xeriscaping, a creative way to reduce outdoor water use through efficient landscaping. Event-goers can expect the following:

  • Local plant vendors providing a variety of less-thirsty plants
  • Educational booths
  • And more

Xeriscaping is based on seven fundamental principles that serve as guidelines on how to plan, plant, and maintain a garden that takes advantage of natural climate conditions to make efficient use of irrigation. Some of the principles include growing “unthirsty” plants, using mulch, and installing proper irrigation.

Proceeds from the plant sale help support educational activities at the Halawa Xeriscape Garden. The open house is co-sponsored by the Friends of Halawa Xeriscape Garden, a non-profit community group that supports educational programs related to water conservation in the landscape. The Halawa Xeriscape Garden is located at 99-1268 Iwaena Street, in Halawa Valley’s Central Park industrial area.

Visitors should park along Iwaena or Iwaiwa Streets. A free shuttle will run along Iwaena Street from 8:30 a.m. to 3:30 p.m.
