Early in the month is a last opportunity to add annuals that will refresh summer-seared gardens with color into fall. Opt for tried and true zinnias in some new colors, tall ‘Goldsturm’ rudbeckia with its yellow petals and black eye or cosmos now available with frilly double blooms. Or experiment with something new like the South African annual Ursinia ‘Solar Fire’ with its golden yellow petals and hot-red centers or sunflowers in mahogany hues. When planting from six-packs or four-inch pots, be sure to water regularly until established. Provide additional moisture if a heat wave strikes.
