Family Scientific Name: Rhamnaceae
Family Common Name: Buckthorn
Scientific Name: Ceanothus fresnensis
Common Name: Fresno Mat
General Distribution: Dry ridge in coniferous forest; 3,000-7,000 feet.
Propagation Goal: cuttings
Propagation Method: seed
ProductType: Container (plug)
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: Hammered: 1/8" screen, 750 revolutions per minute; small clipper: screen size #8 & 1/2", air 100% open. Separation poor.
TYPE OF MATERIAL COLLECTED FOR PROPAGATION: Cuttings, seed.
PROPAGATION METHOD: Cuttings: All leaves except one or two on top were cut off. Stems were cut to approximately six inches in length, and each was dipped 1/2 inch into a hormone powder. The cuttings were then planted 3 or 4 nodes into the soil medium of 5 parts perlite to 1 part peat and placed in the greenhouse side table, directly on the bottom heating coils whose temperature was set at 70§F. Misting was set for 4 seconds at 10-minute intervals. Green-house temperatures averaged 78§F high and 62§F low. The grow lights were on 14 hours each 24 hours. Due to some browning and drying of top leaves, misting was adjusted to keep leaf surface moist.
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: Cuttings: two strengths of Hormex #16 and #3 were used. Seeds: 3 months cold stratification at 35§F mixed with moist vermiculite in a sealed plastic bag.
Growing Area Preparation/
Annual Practices for Perennial Crops:		 METHOD OF GROWING:Data not available at the Lockeford Plant Materials Center.
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 stor-age requirements.

ESTIMATED PROPAGULE STORAGE POTENTIAL: Propagules not stored for any significant time.
