Clusters of large green leaves close to the ground sprout yard-tall stalks of blue, purple, pink or white flowers. But delphiniums take a little time to grow. Recently a shoot grew from the plant that produced a white rose. Oleander caterpillars are invading my plantings. I have tried oil sprays, but they don't seem to help.
Chances are it's one of the sedges, which looks like grass.
Unlike most established grassy weeds, the sedges can be controlled in home lawns. Certainly one or more can be found in the selection available for spring planting. Every gardener should be trying to cut back on water usage. One way is to reduce the area of the landscape devoted to turf or to select a drought-tolerant species. Of all the grasses commonly grown as home lawns, bahia is the most drought tolerant.
