Synopsis: Bring on the sun. Bring on the heat. Bring on the drought-resistant Salvia groundcovers.Flowers by the Sea offers a short list of top groundcovers from around the world for fighting drought. They come from Asia, California, Mexico and Morocco in lavender, purple and pink to do battle against the boring brown caused by water shortage. Similar to gravel, bark chip or pine needle mulch, these groundcovers discourage weeds, cool soil, conserve moisture and add color to gardens. They are living mulch.

Flowers by the Sea has organized a short list of top choices to form an international team of drought fighters. They come from Asia, California, Mexico and Morocco in lavender, purple and pink to do battle against the boring brown caused by water shortage.

Similar to gravel, bark chip or pine needle mulch, these groundcovers discourage weeds, cool soil, conserve moisture and add color to gardens. They are living mulch.

Removing an Outdated Groundcover
Although turfgrass is the most familiar groundcover in America, it didn't become dominant until the late 1800s when lightweight manual lawnmowers became prevalent.

Previous to the 19th century, few common people in Europe or America had grass surrounding their homes. Lawns were a luxury of wealthy landowners, who could afford to surround part of their estates with landscaping instead of crops and kitchen gardens.

Unfortunately, most turfgrasses consume too much water to be practical when drought drags on or where climate is persistently dry. Consequently, many homeowners in the West are removing all or part of their lawns and replacing them with low water landscaping (xeriscape), including mulch and groundcovers.

Depending on local rainfall, water shortages and types of plantings, xeriscapes may receive regular but infrequent watering or no supplemental irrigation at all. The latter are often referred to as "dry gardens."

Tips for Successful Xeriscaping
Important suggestions to remember when xeriscaping, include:

Amending Soils. Mix fine grit or pea gravel into your soil if it is clay that doesn't allow plant roots to drain quickly.

Spacing. Space sages based on their size at maturity rather than jamming them together to speed up coverage. Crowding plants may increase future problems with disease, pests and pruning.

Using Mulch. Xeriscape minimizes or eliminates the need for mowing. Similarly, groundcovers decrease another expensive and time-consuming task -- the need to purchase and spread mulch annually. However, that doesn't mean that you can eliminate mulch altogether. Spread mulch around your plantings when they are becoming established, but don't cover the area near their stems where crown rot may occur from puddled water.

Selecting Best Mulch. Gravel is the best mulching material for drought-tolerant sages, because they need its mineral content and the better drainage it provides. Overly damp organic mulches may lead to mold.
