'After Dark' is a compact dark-leaved sedum. Deep purple foliage is near-black, with the summer sun bringing out the darkest color. In fall clusters of black buds will open to garnet red flowers. Dark red seedheads remain for attractive fall and winter interest.
Tall, upright sedums form substantial clumps of foliage which can be substituted for shrubs in the landscape. Their stout, sturdy stems support the massive flower heads which develop in summer and burst into bloom in fall. If left standing, they provide winter interest and food for birds.

Sedum is one of the most popular perennials grown in American gardens because it is very easy to grow and hardy in most areas of the country. Because of its thick, succulent leaves which can store water, sedum is drought tolerant. It should be sited in average to poor soil that is well-drained. Plants grown in rich soil tend to be lanky and open. Most varieties should be grown in full sun to light shade. The lower growing types, however, will survive in partial shade.
Pinching the taller varieties back by half in early summer will help prevent them from splitting. This plant is not usually bothered by pests or diseases. The seed heads of the taller varieties provide excellent winter interest and food for birds. Remove them in spring when the new growth begins to show.
Container:
Premium 1 Gallon Pot
When to Plant:
Summer to late summer
Finish:
10-12 weeks
Notes:
Bulk in summer for a full plant the following spring.
Container:
Premium 1 Gallon Pot
When to Plant:
Spring to late spring
Finish:
8-12 weeks
Growing Temperature:
70-75° F days
55-65° F nights.
Soil PH:
5.8-6.5
EC (What is EC?):
2.0-3.5 pour through method
Fertility:
Needs 100-200 ppm fertilizer for optimal growth.
For Controlled Release or Slow Release Fertilizer, see your preferred supplier for recommended rates for incorporation or top dressing, as it varies by fertilizer.
Vernalization:
Not required for flowering, however larger plants with better branching and form will occur with vernalization.
Pests & Diseases:
Aphids are the primary insect pest.
Mildew can be problematic and typically presents as scabbing on sedum, preventative fungicide applications are recommended. Sedum can also succumb to crown rots caused by Fusarium and Rhizoctonia, and to stem rot (Colletotrichum).
Potting & Timing:
Some root trimming may be necessary at planting time to fit into the container.
Warm and slightly dry conditions after transplanting speeds rooting and growth.
Moisture:
For potting soil use professional planting media.
Avoid overwatering, extended periods of wet soil will be detrimental and may result in rot.
Planting Level:
Place crown just at or below soil level, plugs with tops at soil level.
PGRs/Pinching:
For plugs, one soft pinch a week after planting helps to encourage branching. A second pinch is optional. Ethephon (Florel) at 500 ppm is also effective at increasing branching. A Daminozide (B-Nine) and chlormequat chloride (Cycocel) tank mix sprayed at 2,000+1000 ppm or Uniconazole (Sumagic/Concise) at 5 ppm will control growth, however, the best growth control method is to grow plants dry.
Configure at 300-600 ppm sprayed 1-2x can increase lateral branching.
Growth regulator rates are suggestions but may vary due to time of year, region and water quality. Trialing is always recommended before applying to an entire crop.
Lighting:
Requires high light in production. In a very high light environment, such as Southern California, plants may need up to 30% shade to protect against sun scorch.
Sedum requires long days to flower. Once pea-sized buds are present plants can be moved to a short day environment, which can actually help to speed flowering and reduce flnal plant height.
