In the garden

Inula racemosa is a tall perennial herb in the daisy family (Asteraceae), native to the range from Afghanistan to China. Plants typically reach about 2.0 m and produce their flowering display between July and September in UK conditions. Its stature and seasonal bloom period make it a candidate where vertical impact is required. Position the plant in full sun and choose a site with moist but well-drained soil; it tolerates sandy, loamy and clay textures. Inula racemosa carries a UK hardiness rating of H6 (very hardy) and corresponds to roughly USDA zones 6–9, so it withstands most British winters short of the coldest exposures. Give extra root space and avoid waterlogged hollows to reduce stress over winter. Allow for its height when siting: it suits the rear of a tall herbaceous border or a naturalistic scheme where tall perennials are appropriate. Because plants can reach 2.0 m, place it clear of low-growing specimens and paths so flower stems are visible and accessible during the July to September flowering season.
