If last summer's impatiens burned out by September, try a new, longer-lasting species, SunPatiens, a cross between traditional New Guinea and wild impatiens.

The plants thrive in full sun and intense heat and humidity for a lengthier life span and fuller bloom season, says Scott Manning, merchandising vice president of live goods and landscape at Home Depot, the sole source for the plant this spring.

The new species, bred in Japan, comes in orange, white, purple and red. The plants can reach 30 inches at full height.

SunPatiens will be available in 1,700 locations by spring's end. A plant in a one-gallon bucket will sell for $3.99-$5.99 (prices vary by region).
