  This elegant perennial is a gorgeous sight in early summer, when the sky rocket-like spires of luminous yellow flowers rise up above clumps of attractively lobed foliage. It's a great plant if you want to inject some structural interest (as well as colour) towards the front of the border, but it can also be grown in a larger pot.
  
  
• Garden care: Deadhead the faded blooms to encourage a second flush of flowers. In autumn cover the crown of the plant to protect against frost damage. keep well watered during dry summers.
