Most asters have quit by the time Tatarian aster gets started. Aster tataricus opens in late September and keeps going through October and into November, still looking fresh at the first frost, on stems that stand five or six feet without a stake. The flowers are small, barely an inch across, lavender-blue with a yellow eye, but they arrive in flat-topped clusters by the hundred, and at that height they read as a haze of color at eye level rather than a mound down at your knees.
A small, slow Japanese cedar that flushes the color of cold lemonade in spring, pale, almost translucent yellow, then settles into soft chartreuse through summer. The foliage stays juvenile throughout, fine and feathery rather than the awl-shaped scale of a mature Cryptomeria, which gives 'Lemonade' a softer presence than most gardeners expect of a conifer. This is texture you can run a hand through.
A rain lily that flowers on a whim of the weather, and a plant that spent nearly forty years under the wrong name. Zephyranthes macrosiphon is a bulbous perennial of the amaryllis family, native to eastern Mexico, grown for vivid rose-pink flowers that open as if overnight after warm-season rain.
Alabama snow-wreath is one of the Southeast's rarest native shrubs and one of the easiest to grow, a combination that ought to put the plant in far more gardens than it occupies. In spring the arching, thicket-forming branches foam with feathery white flowers, and the trick of them is that there are no petals at all: the show is pure stamen, dozens of white filaments per bloom spraying out against five small greenish sepals, like little bottlebrushes of light along the stems.
