Common Name:	Jame's saxifrage
Species Code:	TELJAM
Ecotype:	Alpine cliff faces, Crazy Mountains, Sweetgrass Co., MT., 3000 m elevation.
General Distribution:	T. jamesii grows in moist rock crevices and talus slopes, often on limestone; from Alberta to South Dakota, south in the high mountains of Montana and east Idaho, Colorado, Utah, and southern Nevada.
Propagation Goal:	plants
Propagation Method:	vegetative
ProductType:	Container (plug)
Stock Type:	800 ml containers
Time To Grow:	11 Months
Target Specifications:	Stock Type: Container cutting.<br> Height: 6 cm<br> Caliper: n/a<br> Root System: firm plug in container.
Propagule Collection:	Vegetative Propagation Method: Pre-Rooting Type of Cutting: Summer softwood herbaceous stem cutting collected in late July or early August.
Propagule Processing:	Cuttings are kept moist and under refrigeration prior to treatment.
Pre-Planting Treatments:	Softwoodstem cuttings were 4 cm long with 4 to 6 leaves, and were treated with 1000 ppm Hormex powder. Cuutings were struck under mist for 4 weeks.
Growing Area Preparation/ Annual Practices for Perennial Crops:	The outdoor mistbed has automatic intermittent mist that is applied at 6 second intervals every 6 minutes. Too frequent misting will result in leaf and stem rot. Misting frequency is increased or decreased according to daily outdoor temperature and wind. Bottom heat is maintained at 21C with heating cables 12 cm beneath rooting medium. Rooting medium is 50% perlite and 50% sand. Mistbed is covered with shadecloth during rooting. After cuttings are potted, they are moved to an outdoor shadehouse for 4 weeks. They are later moved to full sun exposure in the outdoor nursery and are irrigated with Rainbird automatic irrigation system in early morning until containers are thoroughly leached. Average growing season of nursery is from late April after snowmelt until October 15th.
Establishment Phase:	Cuttings that were pre rooted were lifted out of mistbed after adequate root systems were formed. Roots originated at the base of the cut and were 3 cm long when lifted for transplanting.
Length of Establishment Phase:	4 weeks
Active Growth Phase:	Cuttings were potted into a well aerated medium of 1:1:1 potting mix:sand:perlite in 800 ml containers. Rooting%: 75% Time to Transplant: 4 weeks
Length of Active Growth Phase:	8 weeks
Hardening Phase:	Irrigation is gradually reduced in September and October. Plants were given one final irrigation prior to winterization.
Length of Hardening Phase:	4 weeks
Harvesting, Storage and Shipping:	Total Time to Harvest: 11 months from cuttings. Harvest Date: June of 2nd year Storage Conditions: Overwinter under insulating foam cover and snow.
Length of Storage:	5 months
Other Comments:	SEED PROPAGATION: Seeds/Kg: unknown % Germination: 25% of fresh seed sown immediately. % Purity: 100% Seed Processing: Seeds are collected when capsules begin to turn brown. Seeds are black at maturity. Seeds are hand cleaned by rubbing the capsules. Seed longevity is unknown. Seed dormancy is classified as non dormant. Seed Treatments: Fresh seed were surface sown as they require light for germination. Germination occurred 3 weeks after sowing at 21C during the day. Gibberellic acid treatment at 1000 ppm for 24 hours is reported to enhance germination.
