About the genus

Strobilanthes is a genus of about 350 species of flowering plants in the family Acanthaceae, mostly native to tropical Asia and Madagascar, but with a few species extending north into temperate regions of Asia. Many species are cultivated for their two-lipped, hooded flowers in shades of blue, pink, white and purple. Most are frost-tender and require protection in frost-prone areas.

In the garden

Strobilanthes atropurpureus sits within the Acanthaceae and the genus Strobilanthes and is valued for its summer flowering run in the UK, which occurs from July to September. Beyond that flowering window, specific requirements such as frost tolerance, soil preference and exact aspect can differ between plants offered by different nurseries, so consult the supplier's label or a specialist reference before planting. Where you place the plant should reflect how you intend to view its July–September flowers: position it where flowering will be visible from patios, conservatory windows or summer seating. If the supplier notes any sensitivity to cold or particular soil conditions, plan protection or container growing so you can move it through colder periods. Timing of routine work is straightforward once the flowering period is known: any pruning or hard shaping is best carried out after September to preserve the current season's bloom. For cultivars or nursery strains under the Strobilanthes name, carry over supplier care notes and update them with observations from your first season to refine siting and winter protection in subsequent years.
