Callistemon citrinus 'Splendens' ('Splendens' bottlebrush)

This showy flowering shrub grows to 8 feet tall and wide and features dark green, compound pinnate leaves on bristly stems and pendant clusters of fragrant, pea-like, rose-pink flowers that are attractive to bees and butterflies in late spring and early summer. The flowers are occasionally followed by bristly, reddish-brown seed pods. Native to the southeastern United States, this aggressive shrub spreads by suckers and is considered invasive in Michigan, New Jersey, Ohio, Pennsylvania, and Washington. All parts of this plant are at least mildly poisonous.

This bold-colored cuphea is a compact, mounding subshrub covered with dark-centered, cherry red blooms centered with a deep purple throat and slightly ruffled petal edges. Flowers are larger than those of the species. This sun-loving plant can reach up to 3 feet in height and width.

Foot-long, rich pink blossoms are nocturnally fragrant and pour out from narrow calyces to terminate in wide, flared openings.

Though its leaves are small, this semi-deciduous shrub stands out in the landscape. Littleleaf cordia has a prolifically branching, slightly open form that looks good year-round. Its roughly textured, dark gray-green foliage contrasts nicely with its coppery brown young stems. From late spring into fall, branch tips bear clusters of pristine, white, funnel-shaped flowers to provide a visually cooling effect during the peak of summer heat. It grows to 6 to 8 feet tall and wide.
