Family Scientific Name: Juncaceae
Family Common Name: Rush
Scientific Name: Juncus parryi
Common Name: Parry Rush
General Distribution: Dry granitic slopes; 6,500-12,000 feet.
Propagation Goal: cuttings
Propagation Method: seed
ProductType: Plug + (container-field grown hybrids)
Time To Grow: 0
Propagule Collection: Collected in the Yosemite National Park.
Propagule Processing: EASE OF COLLECTION: Collection and reestablishment were carried out by Yosemite National Park; data not available at the Lockeford Plant Materials Center.
METHOD OF CLEANING: (1990) Hand-screened with size 1/12 screen. Ran through small clipper using screens: 1/16 X 1/4 top and 1/22 bottom, air closed. Cleaned over and over to remove inert. Difficult to remove stems from seed.
TYPE OF MATERIAL COLLECTED FOR PROPAGATION: Seed, plant divisions.
PROPAGATION METHOD: Division propagation begun in January. Divided in two, plants were then placed into cold frame for 7 days and then moved into lathhouse. Care must be taken to plant exactly at the crown; Juncus parryi had 65% mortality caused by planting too deep.
NUMBER OF SEEDS PER POUND: Quantitative values for seed/lb. could not be found.
PERCENT GERMINATION: Quantitative values for seed germination could not be found.
Pre-Planting Treatments: PRETREATMENT USED: Divisions: placed into Vitamin B-1 solution for 15 minutes to help prevent transplant shock. Seed: none.
Growing Area Preparation/
Annual Practices for Perennial Crops:		 METHOD OF GROWING: Collection and reestablishment were carried out by Yosemite National Park; data not available at the Lockeford Plant Materials Centers.
Harvesting, Storage and Shipping: SEED MATURITY DATE: Quantitative values for date of maturity could not be found.

STORAGE REQUIREMENTS: Longevity of seed unknown. No known special storage requirements.

ESTIMATED PROPAGULE STORAGE POTENTIAL: Data unavailable at date of publication.
