Family Scientific Name: Asteraceae
Family Common Name: Composite Family
Scientific Name: Solidago rugosa P. Mill.
Common Name: Rough-stemmed goldenrod
Species Code: SORU2
Ecotype: Mt. Desert Island, Maine
General Distribution: Rough-stemmed goldenrod is found throughout the United States.
Propagation Goal: plants
Propagation Method: seed
ProductType: Container (plug)
Time To Grow: 0
Target Specifications: Stock Type: Plant plugs, 1" x 1" x 4" cell size. Height: Approximately 4 to 6 inches. Herbaceous perennial. Root System:Firm root plug for a greenhouse crop plant.
Propagule Collection: Collected in Acadia National Park, Maine by Martin van der Grinten in October by hand harvesting.
Propagule Processing: Seed Processing: Allow all the seed to dry after harvesting. Material is hand rubbed on a rubbing board and then run on the Clipper (office model) seed cleaning machine, using 1/19 round top screen, blank bottom screen with the air closed off. When the seed is harvested by a combine from production fields, it is laid on tarps and allowed to completely dry. Once dry, the material is run across a scalper with a 8/64 round screen to remove the large sticks and stems. Next it is run across a seed cleaner (Clipper - Midget II model), with a top screen of 8/64 round, blank bottom screen and the air 15% open.Then a second run is made through the Clipper with a 1/25 round top screen, blank bottom screen and the air 5% open. The harvest weight was 55 pounds and after processing, it was 21 pounds. The seed test had 16% pure seed and 84% inert matter. The seed is so small that it is hard to clean.
Seeds: 21 lbs.
%Purity: 16%.
Pre-Planting Treatments: Seed Treatments: None. There is very low seed viability.
Growing Area Preparation/
Annual Practices for Perennial Crops:		 Propagation Environment: Greenhouse for seeding at 70øF and lathe house for growing and hardening off.

Seed Propagation Method: Plants grown in Rootrainers. The Rootrainers (bookplanters) allow for the plug to be removed by the root system.

Container Type and Volume: Rootrainers. 1" x 1" x 4" cell size.

Growing Media: Metro-Mix 360 media.
Establishment Phase: Sowing Date: Start plants in greenhouse in February for spring planting.

Sowing/Planting Technique: Hand sowing with a light layer of Metro-Mix applied on top after seeding, followed by a through watering. Try to sprinkle 4 to 5 seeds per cell.

Establishment Phase: Rootrainers need to be watered regularly. Germination is relatively uniform. Greenhouse temperature should be 70øF. Germination occurs in one to two weeks.
Active Growth Phase: Rapid Growth Phase: Monitor watering. Fertilization with Miracle-Gro can be applied. Plants can be thinned to 2 plants per cell.
Hardening Phase: Hardening Phase: The Rootrainers are moved from greenhouse to outside lathe house in early spring, prior to being transplanted. Plants can be fertilized with Miracle-Gro while in lathe house.
Harvesting, Storage and Shipping: Total Time To Harvest: Harvest in late fall (October). This seed can be harvested by combine with the seed immediately spread out on the floor to dry.

Storage Conditions: Store dried seed in cooler at 40øF.
