If you haven't already taken a trip to the Cuyamaca College Water Conservation Garden, it is well worth a visit. They have a variety of display gardens showing off beautiful xeriscape design options. Their demonstration gardens teach about composting, how much water different varieties of turf use, and how to attract birds and butterflies to your garden. The garden is large, kid friendly and handicap accessible, so it is agreat day trip for the whole family.
My favorite thing about this garden: it is a great place for people to see that drought tolerant plantings can be beautfil! Most of the plants are tagged, so you can collect ideas about what species you like. The different gardens show off plantings from Meditteranean climates around the world. Want to see what a California native plant garden can look like? Or plants from Australia, New Zealand, South Africa? They have an area dedicated to plantings in pots and anoher to common groundcovers.
They also have many classes and festivals throughout the year. See their schedule for more information. Or just check out their web site.
