Topspin™ Scarlet Begonia

Topspin™ Scarlet Begonia is an early-flowering, mounding wax begonia in Syngenta Flowers’ Topspin series, selected for bedding and container color. Its scarlet blooms stand above green foliage, and the cultivar is part of a series bred for performance in sun or shade. ## Flowers and placement Syngenta identifies Topspin as an early Begonia semperflorens F1 with mounding growth and lists this exact color selection in its seed catalogue. Use it in seasonal beds, packs, and containers where a compact flowering accent is useful. The [Syngenta Flowers catalogue](https://online.flippingbook.com/view/521795265) provides the cultivar identity and series habit; its [Topspin culture guide](https://www.syngentaflowers.com/ams/sites/g/files/kgtney2381/files/file_field/import/field_media_link/sites/g/files/zhg721/f/media/2020/02/16/culture_seed_begonia_topspin.pdf) covers the series’ garden use and growing conditions. ## Growing conditions Wax begonias are tender perennials commonly grown as annual bedding plants in climates with frost. The [RHS profile](https://www.rhs.org.uk/plants/25707/begonia-semperflorens-hort/details) describes flowers from midsummer into autumn and recommends moist but well-drained soil. The breeder lists Topspin for sun-to-shade exposure; afternoon shade can help in hot sites. ## Maintenance Water when the soil begins to dry, especially in pots, while keeping the root zone draining freely. Avoid leaving containers waterlogged. Plant outdoors after frost danger has passed, and remove damaged growth as needed. In cold-winter regions, treat it as seasonal bedding or protect it from freezing.
