Get the look: autumn spectacular

A final flourish of colour illuminates the main borders at RHS Garden Harlow Carr in North Yorkshire – here’s our selection of key plants to get the look

Persian ironwood

Otherwise known as Parrotia persica , the Persian ironwood is one of the very best trees for autumn colour. It can be quite wide-spreading so if you have a small garden, choose the variety 'Vanessa' , which is more upright and takes up less room.

Monkshood

Monkshood is a reliable late-season performer

A closer look at the flowers gives a clue as to why Aconitum carmichaelii is also called monkshood. It's a reliable (a flower that lives for more than two years) bearing blue-purple flowers in September and October. It's poisonous so is best planted at the back of a border, away from passers-by, but still there for the bees and butterflies who love it!

A galaxy of grasses

Grasses add movement and sparkle in autumn sunshine

Grasses really come into their own in the autumn months. Here the purple moor grass ( Molinia caerulea ) in the foreground and golden oat grass ( Stipa gigantea ) show off their golden colours, waving in the breeze and sparkling in the slanting autumnal light. Their delicacy contrasts perfectly with the solidity of the dark green box topiary cones.
