Want a tropical look that's hardy to zone 6? Look no further than 'African Night'. The name alludes to the rich, burgundy leaves that emerge in early summer. By the time the flowers spikes appear in late summer, the foliage will lighten in intensity. Rosy pink flowers are produced on dark burgundy stems with matching burgundy leaflets at the top of the flower spike. Like other late season bloomers such as Hibiscus or Perovskia, this will be one of the last to emerge in spring. This native of South Africa is called a Pineapple Lily for good reason-the inflorescence at the top of the flower scape looks like a tropical fruit.
