When choosing plants for a specific location or
function, we need to be careful to consider many factors,
including size at maturity, water requirements,
hardiness, and color. We've organized the plants on this
page into two main categories based on water
requirements, because for those of us living in San
Diego's North County, this should usually be our number
one concern. We've also included recommendations for
selecting plants within each category based on the
predominant color themes. If you have questions about our
recommendations, send them to me at holmes@holmeslandscape.com.
