Autumn Joy Sedum

Balancing your garden across the seasons is an on-going project for everyone. It’s pretty easy to build a garden that looks great during spring, but increasingly hard to keep going as the seasons come along.

But not always, and you can bring true joy to the weeks of fall with the Autumn Joy Sedum, and have attractive planting through summer too. For long-term beauty this is a plant that is hard to beat, and one that’s easy to grow too. From the first blue-green leaves of the spring growth, through the developing broccoli-like green stage of flower development in summer, to the gorgeous changes through pinks to deep burgundies of fall, this is a plant that will please you every day you walk by it. The ease of growing it and how little it asks for will please you too, you can be sure of that. The ‘perfect perennial’ if ever there was one, this is a plant that belongs in every garden, and never tires, no matter how long you grow it for.

Growing Autumn Joy Sedum

Size and Appearance

Autumn Joy Sedum is a clump-forming herbaceous plant that sprouts each spring from a perennial root. It forms a cluster of upright stems that are covered in fleshy leaves forming pairs or trios all along the stems. The leaves are wedge-shaped, between 2 and 4 inches long, with a scalloped edge at the top, and they are soft green with a blue-white powdery coating. During the early part of the year this clump of foliage is a valuable complement to the other plants around it. The plant is between 1 and 2 feet tall and wide, becoming a little larger and more vigorous each year.

By mid-summer the ends of every stem has grown a flower head, which at this time resembles a clump of broccoli. Greenish-blue at this point, these early flower buds are also attractive, complementing everything around them. In late summer the first hint of color begins, and the heads have now flattened to be up to 6 inches across, packed with hundreds of tiny star-shaped flowers. They begin to turn rosy-pink, darkening gradually as the nights begin to cool, until by mid-fall they are a spectacular warm red, between ‘burgundy’ and ‘brick’. These warm and delicious colors are perfect in fall, and really make a spectacular display. There is never a moment, from spring to the first snow, when this plant doesn’t look attractive. In late fall the flower heads become brownish and in warmer areas they add lots of winter interest too. When the flowers begin to open they are a magnet for pollinators, from bees to butterflies.

Using Autumn Joy Sedum in Your Garden

The versatile Autumn Joy Sedum is as home in your flower and shrub beds as it is in a rock garden or planter box. Grow it in the front of your beds – it is always an attractive foreground, and turns into a major display in fall. It is a wonderful companion for ornamental grasses, other perennials, or small shrubs. It thrives in dry, difficult areas, turning them from ‘drab’ to ‘delightful’ with ease.

Hardiness

Autumn Joy Sedum grows almost everywhere, from zone 3 to zone 9, and it is as happy in arid parts of the country as it is in heat and humidity, or cooler, damper areas.

Sun Exposure and Soil Conditions

Full sun is the rule for Autumn Joy Sedum. Shade will weaken it, making it floppy and pale, with smaller flowers that won’t develop their full potential. It grows in just about all soils that are well-drained, from heavy clays to sandy gravels. It grows in shallow, rocky soils too. In poor, dry soils the clumps will often be smaller, but just as attractive. In richer garden soils they will be larger – so large they can need some support – so try to find a balance that isn’t too rich – manures are not needed. Once established this plant is very drought resistant, withstanding long periods of heat and drought.

Maintenance and Pruning

Pests and diseases are virtually unknown, unless the soil is too wet. It isn’t eaten by deer or by rabbits, and it isn’t toxic to humans or pets. At some time between late fall and early spring, cut off the dead stems to an inch or so. That’s it – no other maintenance is needed. In richer soils, it can become floppy, but a couple of bamboo canes and a length of string will soon fix that problem – just support it, don’t put it into bondage by tying it tightly.

History and Origin of Autumn Joy Sedum

The Autumn Joy Sedum is a descendent of a plant today called Hylotelephium spectabile. This plant was called Sedum spectabile for a long time, but DNA research has proved it isn’t a sedum at all. It grows naturally in China and Korea, and seems to have first been grown in France in the 1860s. This was a time when there was growing interest in perennial plants, particularly in England. Georg Arends was the son of a German family who owned a nursery, and from1885 he lived in England for a time, picking up that interest, which was very different from gardening in Germany. When he returned home in 1888 he set up his own nursery, dedicated to flowering perennial plants. During his life he created many garden plants we still enjoy today, including Astilbe and Phlox. He also developed sedums, and working with Sedum spectabile he created hybrids – we don’t know the exact parentage – of which the most famous is one called ‘Herbstfreude’. He first offered it for sale in his catalogue in 1955. For a long time, outside Germany, it was called ‘Autumn Joy’ or sometimes ‘Indian Chief’, but today we honor Arends by giving it the correct name. From it other plants have been created, and they are all placed together in the Herbstfreude Group of Hylotelephium, since we don’t know the exact parentage.
