Alonsoa warscewiczii is the only species of this Peruvian genus grown in the United States, though several cultivars have been developed from it. A compact bushy plant reaching 1-3 ft (30-90 cm) high, it has glossy dark green oval leaves and red stems. The scarlet flowers with yellow centers appear from midsummer to midfall, adding color to formal beds, borders, and containers. The plants are tender perennials but flower like annuals in their first year from seed.
