1Lawns composed of turf grasses are the most functional, but also the most demanding forms of groundcover. That is old news. There are so many other less demanding low growing plants that that can cover the ground in areas that are not used like lawns are. Sometimes they work nicely just to control weeds. Sometimes they help to control erosion on otherwise unlandscaped hillsides.

Like all other plants in the garden, groundcover plants must be appealing. There is no point in growing plants that look no better than the bare soil they are intended to obscure, or the weeds they are intended to control. Some provide good foliage. Some bloom nicely. Many do both. Although not as resilient to wear as turf grasses, some groundcover plants tolerate some degree of traffic.

There are of course all sorts of groundcover. Only a few want as much water as lawns need. Some need no watering at all once established. Some are low growing shrubbery like sprawling forms of ceanothus, coyote brush, cotoneaster, coprosma and juniper. Others are vines like honeysuckle and ivy. Some of the best are creeping low perennials like iceplant, gazania and African daisy.

Low growing shrubberies may not be practical for confined spaces. When they run out of room to grow laterally, they tend to pile up on themselves, and some types can eventually get quite deep. Some types look silly if pruned around the edges for containment. Vines however need to be pruned around the edges, as well as out of trees and shrubbery. Some vines eventually get deep too.

Sprawling perennial groundcovers are the lowest and tidiest of groundcovers. They might not be as practical as shrubbery or vines for large areas, but are more often the better options for tight spaces. They do not mind getting pruned around the edges, and generally do not need any other pruning, although some look better if mown annually. Periwinkle and Saint John’s wort can get deep enough to get sloppy. Many other perennial groundcovers stay low enough to barely get disheveled by light trampling.2

      1. Well, periwinkle, Saint John’s wort and English ivy out in the forest are all in the wrong place. English ivy climbs high into trees, even the redwoods. It crowds out native vegetation. I like it in the landscape, but many of my colleagues really want nothing to do with it.

    1. Oh, that is just baby tears. It grows like a weed where the ground is always damp, but can get roasted instantly if the ground ever gets dry. Consequently, it has limited application.

  1. I dearly love groundcovers… I even have a nice little lawn of Australian violet, self-heal, coastal strawberry, blue star creeper and clover that takes any amount of trampling! But you really do need to understand how each grows and use them in the right situations or they can sometimes be more bother than they are worth. But there is nothing better at keeping weeds down and offering beauty at the same time. You can’t say that for mulch.

    1. At my former home, I had a small lawn of Algerian ivy, the sort that everyone jokes about nowadays. However, I really liked it! I dislike lawn that does not get used. It needs so much mowing and watering. The Algerian ivy only got pruned around the edges. It was a lot of work, but less work than the grass lawn, and it looked great. (I do not think I would have wanted over a larger area, because it would have been a waste of space.)
