Family Scientific Name: Caprifoliaceae
Family Common Name: Honeysuckle Family
Scientific Name: Lonicera hispidula (Lindl.) Dougl. ex Torr. & Gray vacillans Gray
Common Name: Hairy Honeysuckle
Species Code: LONHIS
Ecotype: Catalina Island, California
General Distribution: Hairy Honeysuckle is found throughout southern California and the Channel islands. On Catalina Island, it inhabits streambanks,canyon bottoms and slopes.
Propagation Goal: plants
Propagation Method: seed
ProductType: Container (plug)
Stock Type: #1 Treepot (173 cubic inches)
Time To Grow: 9 Months
Target Specifications: Height: N/A<br> Caliper: N/A<br> Root System: Firm root plug in container.
Propagule Collection: Fruits are hand collected when they are fully matured. We have collected fruits in September and October. Seeds are brown at maturity.
Propagule Processing: Fruits dry in paper bags in a warm, dry room. We clean the seeds by running fruits through a modified blender briefly to remove pulp from the seeds. We allow seeds to dry on wooden screens and use a seed blower set at 30 to remove chaff.
We have also rubbed fruits through a large screen with water to remove pulp, then screened pulp through a US Standard test sieves (#10 and #18). Seeds dry for several weeks following cleaning.
After seeds have been cleaned, they are stored under refrigeration in air tight glass containers at 40 F and 40% RH. With 6 collections, seeds average 0.93 grams per 100 seeds.
Pre-Planting Treatments: We have used a Physan fungicide soak or a 3 minute 5% bleach solution to surface sterilize seed coats prior to testing or sowing.

Germination percentage: 100%
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 compound. 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 winter and early spring months in a shadehouse were they remain for several weeks. Flats and containers are filled with a 1 inch layer of special seed germination mix of 1:1 (v:v) Sunshine Professional GrowingMix 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.
Length of Establishment Phase: 2 months
Active Growth Phase: After seedlings are well established and have at least 2 true leaves, they are transplanted into 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.
Seedlings are ready for transplanting into 2 inch containers containers 8 to 10 weeks after germination.

Following transplanting, seedlings are moved to another shadehouse with more temperature variance where they remain for several weeks.

We shift 2 inch container plants once they are root tight to #1 treepots (173 cubic inches) after 9 weeks( end of May). We top prune as needed to encourage branching.
Length of Active Growth Phase: 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 compound.
Length of Storage: Variable; depends on out planting date.
