JULY 2016 – When we think of low-water, or drought-tolerant plants, we often think of dry, barren landscapes. But, do we really have to sacrifice color to save water in San Diego County? The answer is NO!
Here are 15 examples of water-saving plants and shrubs you can use to add pops of color to your low-water landscape.
1. Prunus Mume ‘Japanese Flowering Plum Tree’
The Japanese Plum is deciduous, dropping leaves annually, and it grows as tall as 20 feet high. A red-leafed beauty, it blooms annually as well, featuring small white flowers from January to March. Though some specimens may produce fruit, it is not edible.

This deciduous tree or shrub can grow as tall as it is wide, as large as 30 feet, depending on the selection and training. Flowers form into clusters, and are available in various colors, including shades of red, purple, or white. It has a long flowering season, lasting from July to September. If trimmed during the dormant season, flowers will bloom even more the following summer.
Full sun. Light shade in hotter areas.
The official flower of the city of La Mesa in East County, California, this evergreen vine thrives in all areas of San Diego. A spring bloomer, the Bougainvillea comes in many colors and can be trained to form as a shrub or climb up a trellis. Color comes from the three large papery bracts that surround small white flowers. This plant does have thorns along its stems, so be careful during pruning season (late winter to early spring).

An evergreen shrub, the Cistus produces flowers during the spring. This plant thrives in Mediterranean climates, and can grow in poor, dry soil or cold, ocean spray winds.

5. Osteospermum Fruticosum ‘Trailing African Daisy’
This plant can cover an area quickly with its trailing, rooting branches (hence the name “Trailing”). Rapid growth makes it a perfect choice for ground cover or for use on slopes and embankments. This happy flower blooms year-round, with the biggest show occurring from November to March. One rooted branch can cover a circumference of 2 to 4 feet and grow up to 12 inches in height. The Trailing African Daisy comes in a variety of colors.

Lantana is fast growing, and shows its beautiful color for an extensive time during summer months. It can be used as a shrub, low hedge, or as an embankment cover.
