Asarina

Asarina is a genus of flowering plants in the family Plantaginaceae. The genus contains several species, native to various regions of the world, including North America and Asia. These plants are commonly known as snapdragons or more specifically, asarinhas, distinguishing them from the more widely known Antirrhinum genus.

The species within Asarina are typically herbaceous perennials or subshrubs, often grown as annuals in cooler climates. They are characterized by their vibrant, trumpet-shaped flowers, which come in a range of colors including shades of purple, pink, white, and sometimes yellow. The flowers usually bloom from late spring through summer, attracting pollinators like bees and butterflies. The leaves are generally opposite, often lobed or toothed, and can vary in texture from smooth to slightly hairy.

Asarina species are cultivated for their ornamental value in gardens, hanging baskets, and containers. They generally prefer well-drained soil and full sun to partial shade. Proper watering is important, as they can be sensitive to overwatering. Propagation is usually achieved through seeds or cuttings. Some species are known for their trailing or climbing habit, making them suitable for cascading displays or for growing up trellises and supports. While closely related to Antirrhinum, Asarina species often possess a more delicate appearance and a preference for warmer conditions.
