In the garden
Indigofera decora belongs to the genus Indigofera and originates from China and Japan; it is grown chiefly for its decorative summer flowering. With a typical height of around 1.0 m it provides a modest vertical element in the border without dominating taller shrubs. Place summer wisteria in a position receiving full sun and use a sandy or loamy soil that stays moist but drains freely; avoid sites that remain waterlogged. A mulch of well-rotted organic matter will help the soil retain moisture while preserving free drainage. The plant is rated H7 for UK hardiness (fully hardy) and corresponds to USDA zones 5–7, which is useful when comparing climates beyond Britain. Because of its compact stature, Indigofera decora suits the front to middle of a sunny mixed border or a low informal screen where summer flowering is wanted. Plant with slightly larger neighbours at the back of the border so it shows to best advantage. A light trim immediately after flowering will tidy growth and help keep stems within the 1.0 m profile.
