The old-fashioned shamrock houseplant is now high fashion. Several introductions from Proven Winners push this group to the fore for its elegant foliage; abundant, delicate flowers; and vigor. Only 6 to 10 inches high with a spread to 12 inches, this plant’s tiny, ¾-inch-wide, bronze-colored leaf clusters and bright yellow flowers are massed on trailing stems that spill over the sides of shaded window boxes and containers.
Noteworthy CharacteristicsNice houseplant.
CareThough this shamrock is frost tender, it is easy to overwinter indoors.
PropagationSow fresh seed or divide rhizomes.
ProblemsFungal leaf spots, powdery mildew, rust, and seed smut are the most common problems, but also watch for spider mites and leaf miners.
