Soil Preference Well draining soil is essential for most of these cultivars. They are quite forgiving with soil types but perform best in lean, mineral soil. Once established, sedum have low water needs and should be allowed to dry completely between waterings. 
Day Length Obligate long-day plants. Plant in full sun. 
Pinching Pinch one week after transplant to encourage basal branching. 
When to Plant Plant anytime from last frost in the spring through to mid summer to allow the plants to establish before the onset of winter weather. 
Harvesting Sedum can be harvested for foliage, in bud, or in flower. It's a very versatile plant. 
Post Harvest Care Cut stems last over a week in the vase. Clean water and the use of a floral preservative will help maximize vase life. 
Diseases / Insects Sedum are quite resistant to most pests and disease. They can be affected by aphids, and fungal issues or root rot if in an area with poor drainage. 
Bailey's Notes

"I think Sedum is the most underrated perennial cut flower! Cut it green, cut it in bud, cut it in flower, cut it as it fades, cut it dry... It just doesn't matter. It bulks up arrangements and adds texture to any arrangement. It's also pretty hard to kill. I have it growing in full shade, full sun, in wet soil, and on top of gravel, and it seems pretty happy everywhere. In general it prefers good drainage and full sun. Clumps get bigger each year."
