Salvia mexicana 'Limelight' Salvia mexicana 'Limelight'
 Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This unusual tender perennial displays an electric color combination when its vibrant purple-blue flowers open from bright chartreuse calyces.  Fortunately, glossy, bright green leaves hold their own until the show gets started in August (and continues until frost). It forms a tall bush, 6 feet tall by 6 feet wide, which is great for the back of the border. Salvias are some of the showiest plants for containers, annual borders, and mixed borders. Butterflies and hummingbirds love them. 
Silphium perfoliatum Silphium perfoliatum
(Cup plant) Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

A coarse but bold perennial giant for the back of the border with yellow, daisy-like flowers in summer. Cups form where the toothed leaves meet the thick stems; birds are said to drink from the water held in the cups. Tough prairie natives that will self-sow, these plants need lots of sun and lots of room—a single plant can reach 7 or 8 feet tall and 6 feet across.
Solidago rugosa 'Fireworks' Solidago rugosa 'Fireworks'
(Goldenrod, Rough-stemmed goldenrod) (30 user reviews)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This eye-catching cultivar has flower clusters that radiate out in all directions and resemble streaming yellow fireworks. Its form is truly unique and enchanting. It reliably provides end-of-season color in blazing shades of yellow. It grows to 5 feet tall and provides good structure in the garden all year.
