Tall clumps of fine, fresh-green, needle-like leaves form weightless scrims of foliage in the border (or vase), contrasting marvelously with bold-leaved companions. Tiny greenish-white flowers appear in late spring, culminating (on female plants) in berries that ripen bright red as the leaves (which are actually modified stems) turn yellow in fall. Zone 3. Propagated from seed. Deep 3.5-inch pots.
