Poor horseherb (Calyptocarpus vialis). It's gotten bad rap. Some consider it an invasive pest. You have seen it often, one of those weeds that, if you live in Austin, is ever present on the periphery, popping up in St. Augustine lawns or clinging to the driveway, an afterthought, like the variety of moss rose (portulaca) that grows out of the cracks in the sidewalk pavement. Yet its miniaturized charm is hard to resist: spritely green foliage dotted with even tinier yellow daisies—that bloom throughout the spring and summer. But it has a role as a viable groundcover plant. It is growing here and there all over my plot, and today I dug up bunches and transplanted them to the front yard which is currently a dirt patch. The plan is to convert much of the front "lawn" to horseherb cover. It can be mowed; takes foot traffic, and tolerates poor soil, drought, and variable light conditions. What's not to like? Since it will be contained between a sidewalk and the driveway, I'm not concerned about its robust spreading by runner. Horseherb's other name is "Straggler Daisy." Clearly this plant needs a PR firm to handle its image and conduct a relaunch under a new and more positive name.
