Sedum Autumn Fire Care
Size and Growth
‘Autumn Fire’ isn’t a large plant, rarely growing more than 24″ inches tall and 18” inches wide.
It’s a slow-growing plant, with herbaceous leaves. The foliage is often a blue-green color, with small, round leaves and thick succulent stems.
Flowering and Fragrance
This plant is a late bloomer, known for the showy flowers it produces in the late summer.
Sedum spectabile ‘Autumn Fire’ has clusters of bright, rosy-pink flowers beginning as green buds at the start of summer.
As the large flower heads open, the rose-colored flowers appear.
Throughout the summer, the color of the flowers gradually change. The flowers go from a bright rose color to a dusty, coppery red adding winter interest.
Light and Temperature
The plant is native to parts of Europe and winter hardy in USDA hardiness zone 3 to 9.
It can last outdoors throughout the winter, even in freezing temperatures. But, grows best in a location with full sun to partial shade.
If grown indoors or on a porch, ensure it receives plenty of sunlight throughout the day, but keep it away from a window with direct sunlight.
Direct sunlight, even through a window, may eventually scorch the leaves.
Keeping the plant in a room kept at standard room temperature should provide an adequate environment, but slightly cooler temperatures during the winter help encourage a fuller bloom.
Watering and Feeding
This is a drought-tolerant plant. As a succulent, autumn fire sedum retains water in its stems and leaves.
Water infrequently to avoid overwatering the plant. The plant needs less watering as it matures.
Young plants may require more watering during the active growth period, but established plants become more drought tolerant.
When grown outdoors, it only needs supplemental watering if it doesn’t get enough rainfall.
In areas receiving less than an inch of rain each week, give the plant a light watering.
Use all-purpose fertilizer once per year. Add the granular pellets to the soil in the spring and cover with 2” inches of mulch.
In the winter, the plant may not need any water.
Pay attention to the leaves. If the leaves start to drop, it may require watering.
Soil and Transplanting
Use well-drained soil. If planting outdoors, space the plants at least 18” – 24” inches apart.
Cover the top of the soil with 2” inches of mulch. The mulch helps retain moisture and prevent weed growth.
After adding the mulch, clear it away from the base of the plant, ensuring it doesn’t touch.
Avoid transplanting the plant. Only repot Sedum autumn fire when the root system outgrows its pot or planter box.
Sedum autumn fire doesn’t need grooming.
