General Distribution: L. utahensis occurs from southern B.C. east to Alberta and south to California, Montana, Wyoming, and Utah. This species occurs in a variety of forest habitats that are vernally moist.
Propagation Goal: plants
Propagation Method: seed
ProductType: Container (plug)
Stock Type: 172 ml conetainers
Time To Grow: 9 Months
Target Specifications: Height: 15 cm<br> Caliper: 7 mm<br> Root System: firm plug in 172 ml conetainers.
Propagule Collection: Fruits are hand collected in mid July when the fruit turns red. Seeds are tan at maturity. Fruit is collected and stored in plastic bags prior to cleaning.
Propagule Processing: Seeds are extracted from the fruit by maceration using Dyb-Vig seed cleaner and screens at NRCS.
Seed Storage: up to 15 years at 1 to 3C in sealed containers.
Seed dormancy is classified as morpho-physiological dormancy.
Seeds/Kg: 718,000/kg
% Purity: 100%
% Germination: 95%
Pre-Planting Treatments: Seeds were treated with 1,000 ppm gibberellic adic for 24 hours, followed by a 48 hour running water rinse. Seeds were placed into a 60 to 90 day cold, moist stratification at 3 C. Seeds germinated at 3C after 60 days of stratification. Do not sow seeds until there is visible cracking or radicle emergence.
Growing Area Preparation/
Annual Practices for Perennial Crops:

Sowing Method: Planting Germinants. Seeds are covered with medium.
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 0.20 gram of Micromax per 172 ml conetainer.
Establishment Phase: Emergence was uniform and complete 2 weeks after planting in the greenhouse. Greenhouse temperatures were maintained at 22C/15C 12 hr day/12 hr night.
Length of Establishment Phase: 4 weeks
Active Growth Phase: Plants were fertilized weekly with 20-20-20 liquid NPK at 100 ppm. Plants were multi-stemmed and root tight in conetainers in 3 months. Plants reached reproductive maturity 1 year after germination in the nursery.
Length of Active Growth Phase: 16 weeks
Hardening Phase: Plants were fertilized with 10-20-20 liquid NPK at 200 ppm during September and October and given one final irrigation before overwintering.
Length of Hardening Phase: 4 weeks
Harvesting, Storage and Shipping: Total Time To Harvest: 25 weeks.
Harvest Date: September
Storage Conditions: Overwinter in outdoor nursery under insulating foam cover and snow.
Length of Storage: 5 months
Other Comments: 3L (1gallon) container stock can be produced in 1.5 years.
