About
Achimenes 'Harry Williams' is a compact, rhizomatous perennial that grows up to 40 cm tall. It features serrated, hairy leaves that are dark green on the top and purple on the underside. From summer into autumn, it produces tubular flowers in a deep purple-red hue, each adorned with speckled yellow markings at the center.
About the genus
Achimenes are perennial plants with rhizomes that store nutrients, producing long, trailing stems. These stems support simple leaves that appear either opposite or in whorls. During the summer and autumn months, the plants produce conspicuous, salver-shaped flowers that emerge from the axils of the leaves.
