Another improvement of the tried and true Sedum Autumn Joy.
Plant Type
All Plants, Perennials Hardy
Hardiness Zone
4-9
Sunlight
Prefers full sun. In shaded conditions the plants tend to open up in the center and flop.
Moisture
average to dry
Soil & Site
average to dry, well drained
Flowers
The 6 inch flat topped inflorescence (convexed cyme) start as white, turns to rosy-red and finishes with a deep bronze-red. Starts blooming mid to end of August and can last through October. Flowers are reported to be larger and hold up better than Autumn Joy. They also seem to have more red in their color.
Leaves
The 2-3 inch long fleshy succulent leaves are sessile with irregular teeth (dentate). Starts out in spring as a mounded plant than the stems stretch to form a small clump.
Dimensions
24 inches by 24 inches, space 18-24" on center
Maintenance
If your plants flop or open up because of the growing conditions I have found that cutting the plants back 50% by the end of May will result in a more compact plant. This does not reduce the flower production. Cutting down the stiff dead stalks in the late fall is a matter of choice. Some people like the dead brown plant for winter interest.
Propagation
Very easy from cuttings or divided in the spring. When dividing the plant be careful the new stems are easily damaged.
Cultivar Origin
Originated at the Norseco Nursery in Quebec, Canada.
Author's Notes
I have grown Sedum Autumn Joy and Autumn Fire. The Autumn Fire does seem to be more compact than Autumn Joy. Best in full sun.
