This new flowering hybrid resists fungus (which can weaken the plant and cause the leaves to shrivel). And, happily, it's self-cleaning.
New Guinea Impatiens
This variety of impatiens, with its showy flowers, is uniquely versatile. It can handle some sun, unlike the more commonly found species, which like only shade. Also self-cleaning.
It's a mainstay of window boxes everywhere, and here's why: This flower comes in dozens of colors and flourishes in many climates. Pelargonium zonale is particularly vigorous. To care for it, simply deadhead and pinch back as needed.
With masses of tiny flowers, Euphorbia hypericifolia is pretty and self-cleaning. And deer will steer clear of it (they don't like the taste).
Purple Fountain Grass
A gracefully arching ornamental grass with fuzzy, rose-colored seed heads, 'Rebrum' can withstand just about anything, including high humidity and wind. It's pest- and disease-free, too.
Prized for its bold, variegated foliage, this two-tone stunner is easy to grow and thrives in summer. It comes in a slew of gorgeous colors. To care for it, deadhead and pinch back as needed.
This cascading beauty, covered in small flowers, makes a great hanging plant. It's self-cleaning and resistant to disease.
This ornamental plant grows extremely quickly. It won't climb walls or trellises, but it will trail beautifully over pots. Lush, dramatic colors include deep purple, bronze, and lime green.
Unlike other begonias, which need to be in the shade, Begonia boliviensis fares well in full sun or partial shade. And it rewards you with a profuse shower of tubular, orange red flowers. It benefits from an occasional pinching back.
This self-cleaning plant has flower petals with multiple colors (like confetti). The strong fragrance of the leaves deters deer, and hot days stimulate it to produce more blossoms, which attract butterflies and hummingbirds.
