Hylotelephium 'Herbstfreude', also known as Sedum spectablis ‘Autumn Joy’, is a fleshy-leaved fully-hardy perennial, forming clumps of blue-green leaves around 60cm tall. They have pretty pink flowers through the autumn, eventually fading to a rusty brown. The plant’s name was recently changed to Hylotelephium, but you’ll usually still find it in nurseries and garden centres as Sedum.
Happiest in a sunny spot with well-drained soil, the plant will also tolerate a more exposed site and is a great option for autumn colour towards the front of a border. It dislikes damp, cold soil. Cut it down to the base in early spring as the new buds start to appear there. The plants are generally pest-free, though vine weevils can be a problem. You can find it on the West Walk in the University Parks.
