Asteraceae (Aster Family)
Depending on your point of view, Straggler Daisy or Horseherb is a pest or a welcome, shade-tolerant groundcover that tolerates moderate foot traffic. If you have a shady lawn anywhere within its range, you probably already have it. It gained in popularity during the growth in interest in native
plants and is now occasionally available for sale at native
plant nurseries (though it is so easy to propagate that you can easily grow it on your own). Thriving in sun or shade, its tiny, yellow daisy flowers add a minute touch of color to shady areas and attract small butterflies like sulfurs and skippers.
Because it is dormant in cold winters, mix with cool-season spring annuals and evergreens for continuous color. In central Texas, Baby Blue-eyes (Nemophila phacelioides
), Widows Tears (Commelina
spp.), False Dayflower (Tinantia anomala
), Violet Ruellia (Ruellia nudiflora
), and sedges (Carex
spp.) are good companion plants for shady areas.
