Family Scientific Name:	Crassulaceae
Family Common Name:	Stonecrop family
Scientific Name:	Sedum roseum (L.)Scop.
Common Synonym:	Sedum integrifolium (Raf.) Nels.
Common Name:	Kings crown stonecrop
Species Code:	SEDROS
Ecotype:	Alpine fellfield, cliff face, Scenic Point, Two Medicine,Glacier National Park, Glacier Co., MT., 2300 m
General Distribution:	S. roseum grows on cliffs, talus, and ridges, generally where it is moist during early summer, in the subalpine to alpine zones. It is found from B.C. to California, east to Alberta, Montana, the Great Lakes region, Maine, and Colorado, Asia and Greenland.
Propagation Goal:	plants
Propagation Method:	vegetative
ProductType:	Container (plug)
Stock Type:	490 ml containers
Time To Grow:	5 Months
Target Specifications:	Stock Type: Container cutting<br> Height: 4 cm<br> Caliper: n/a<br> Root System: firm plug in container.
Propagule Collection:	Vegetative Propagation Method: Pre-Rooting Type of Cutting: Herbaceous stem cuttings taken in late August. Cuttings are 2 to 4 cm in length.
Propagule Processing:	Cuttings are stuck in rooting medium immediately after collection.
Pre-Planting Treatments:	Succulent stem cuttings can be taken any time of year. Cuttings are treated with 1000 ppm Hormex rooting powder and struck in moist sand. Intermittent mist is not necessary. Cuttings generate roots along the stem in 2 weeks. Rooting %: 100%
Growing Area Preparation/ Annual Practices for Perennial Crops:	Greenhouse and outdoor nursery Use a well aerated rooting medium of 50% sand and 50% perlite. Trays are kept in a greenhouse and watered by hand to keep rooting medium evenly moist. Because this is a succulent, frequent intermittent mist should not be used.
Establishment Phase:	After cuttings are well rooted in 2 to 4 weeks, they can be moved to the outdoor nursery.
Length of Establishment Phase:	4 weeks
Active Growth Phase:	Growing medium used is 6:1:1 milled sphagnum peat, perlite, and vermiculite with Osmocote controlled release fertilizer (13N:13P2O5:13K2O; 8 to 9 month release rate at 21C) and Micromax fertilizer (12%S, 0.1%B, 0.5%Cu, 12%Fe, 2.5%Mn, 0.05%Mo, 1%Zn) at the rate of 1 gram of Osmocote and 0.25 grams of Micromax per container. Cuttings were irrigated after potting.
Length of Active Growth Phase:	12 weeks
Hardening Phase:	Plants are fertilized with 10-20-20 liquid NPK at 200 ppm during August and September. Plants were given one final irrigation prior to winterization.
Length of Hardening Phase:	4 weeks
Harvesting, Storage and Shipping:	Total Time To Harvest: 5 months from cuttings Harvest Date: August Storage Conditions: Overwinter under insulating foam cover and snow.
Length of Storage:	5 months
Other Comments:	Seed Propagation: Hand collect mature follicles when they begin to tan and split open at the top. Seeds are brown at maturity. Seeds are collected in late August at high elevations. Seeds are cleaned using a hammermill, blower, and screens. Seed longevity is unknown. Seed dormancy is classified as nondormant for many temperate Sedumspecies. Seeds/Kg: unknown
