You may have decided to replace your thirsty traditional lawn in your new sustainable landscape. What options are available for some kind of natural plant element rather than covering the same area with hardscaping?
Consider replacing the lawn with a groundcover type plant. There are many good choices that make good lawn substitutes and grow well in San Diego’s six climate zones. Several of them fall into the very low or low Plant Factor categories, which means they require less water than the same amount of grass.
Very Low Plant Factor choices include:
- Silver Carpet (Dymondia margaretae)
- Bluff California Lilac (Ceanothus maritimus)
Low Plant Factor choices include:
- Pink Yarrow (Achillea millefolium rosea)
- Gold Coin Plant (Asteriscus maritumus)
- Sundrops (Calylophus hartwegii)
Carmel Mountain ceanothus
- Dwarf Mat Rush (Lomandra longfolia)
- Bee’s Bliss Sage (Salvia)
- Wooly Thyme (Thymus pseudolanguinosus)
- Blue Chalksticks (Senecio serpens)
Moderate Plant Factor choices include:
- Creeping Manzanita ‘Carmel Sur’ (Arctostaphylos edmunsii)
- Beach Strawberry (Fragaria chiloensis)
- Pink yarrow, sages, and lilacs also support the lifecycle of butterflies, which are important pollinators.
