Buddleja have masses of sweetly scented flowers that are very attractive to butterflies, hence the common name. Buddleja davidii ‘Joan’ comes from the garden of Joan Head in the UK and with its upright branches in full flower ‘Joan’ makes a stunning sight in late spring and summer when the branches are covered in masses of huge purple, fragrant blossoms. It likes a full sun position with well drained soil and an annual feed with Osmocote Slow Release. It will grow to around 4m tall and about 2.5m wide. It is hardy to most situations and will respond well to an annual prune. Remove spent flowers to prevent self seeding.
Use as a specimen plant or part of a large cottage style garden. Surround with other Buddlejas or Lavandula ‘Avonview’ and Lavandula ‘Somerset Mist’. Alternatively plant it as a backdrop to a bed of Heuchera and winter flowering Rosmarinus cultivars like ‘Salem’
