Family Scientific Name: Apiaceae
Family Common Name: Carrot Family
Scientific Name: Sanicula arguta Greene ex Coult. & Rose
Common Synonym: Sanicula simulans Hoover
Common Name: Sanicle
Species Code: SANARG
Ecotype: Catalina Island, California
General Distribution: Sanicle is found throughout southern California and the Channel islands. On Catalina Island, it inhabits slopes, ridges and sea bluffs.
Propagation Goal: plants
Propagation Method: seed
ProductType: Container (plug)
Stock Type: Deepot 40
Time To Grow: 1 Years
Target Specifications: Height: N/A<br> Caliper: N/A<br> Root System: Firm root plug in container.
Propagule Collection: Seeds are hand collected when they arefully matured. We have collected seeds from May to June.
Propagule Processing: Seeds dry in paper bags in a warm, dry room. We clean the seeds by rubbing dry fruits with a rubber mat and block to remove prickles from seed coats. We sift material through a Graimans brand "K" pan. We blow material at up to 20 setting to remove empty seeds and any remaining debris.
After seeds have been cleaned, they are stored under refrigeration in air tight glass containers at 40 F and 40% RH. With 8 collections, seeds average 0.52 grams per 100 seeds.
Pre-Planting Treatments: We have used a weak 30 minute Physan disinfectant soak or a 3 minute 1% bleach solution to surface sterilize seed coats prior to testing or sowing.We treat seeds in June soon after they are collected.

Germination percentages have ranged from 72 to 92%.
Growing Area Preparation/
Annual Practices for Perennial Crops:		 The James H. Ackerman Native Plant Nursery is located on Catalina Island off the coast of southern California. From 1993 to 2004, the average maximum and minimum temperatures have been 75.4 F and 46 F, with an average of 361 frost free days per year and annual rainfall of 14 inches.
The facility is comprised of shade houses, mist propagation house, and an outdoor growing area. All propagation environments are utilized at different stages of seedling growth to provide for the variance in temperature and shading requirements needed during the growing season. We irrigate all containers with an overhead emitter system in the shadehouses and use a drip system or hand water in the outdoor nursery.
Establishment Phase: Seeds are germinated during June in a shadehouse were they remain for several weeks. Seeds are directly sown into flats filled with a 1 inch layer of special seed germination mix of 1:1 (v:v) Sunshine Professional Growing Mix and sand on top of 4:1:1 (v:v:v) peat, perlite, and organic compost. We incorporate Osmocote time release fertilizer (9 month release rate) (14 N:14P2O5:14K2O) at the rate of « cup per 0.75 cubic yard of medium. Seeded flats are watered with an overhead emitter system as needed.
Seeds germinate 2 to 8 weeks after sowing, although germination may continue for up to 5 months.
Length of Establishment Phase: 1 to 5 months
Active Growth Phase: After seedlings are well established and have at least 2 true leaves, they are transplanted into Deepot (40 cubic inches)containers filled with a growing medium of 4:1:1 (v:v:v) peat, perlite, and organic compost. Osmocote time release fertilizer (9 mo release rate) (14 N:14P2O5:14K2O) is incorporated into the medium at a rate of
of « cup per .75 cubic yards of medium.
Following transplanting, seedlings are moved to another shadehouse with more temperature variance where they remain for several weeks.
Transplants must be watered carefully, it may be est to allow seedling to dry down during summer and water only to keep root systems viable.
Length of Active Growth Phase: 5 to 6 months
Hardening Phase: Any nursery stock grown under shadehouse conditions are hardened by placing them in full sun exposure for a minimum of 2 weeks prior to outplanting.
Length of Hardening Phase: 2 to 4 weeks
Harvesting, Storage and Shipping: Containerized seedlings are over wintered directly in the open growing area.
Length of Storage: Variable; depends on out planting date.
