This tall yellow flower is sometimes called Church Steeples or Sticklewort. It is a perennial and can grow up to 100cm but more usually around 50cm. Its seeds have spikes that promote dispersal by animals and is a good source of pollen for insects and butterflies. Flowering in June, July and August it has a slightly fruity scent.
Often found in verges and margins of woodland or fields, growing well in dry pastures and rough areas.
Sow in the Spring or Autumn onto non-acidic soils and it should thrive if the area is not deeply shaded or poor to drain. It spreads naturally by hooking onto passing animals.
