Family Scientific Name: Asteraceae
Family Common Name: Sunflower Family
Scientific Name: Madia glomerata Hook.
Common Name: Mountain tarweed
Species Code: MAGL2
Ecotype: Seeds were collected from Lane Co., Oregon near Eugene.
Propagation Goal: seeds
Propagation Method: seed
ProductType: Propagules (seeds, cuttings, poles, etc.)
Time To Grow: 0
Target Specifications: Grow plugs to be transplanted into a field covered with weed fabric (to collect the seeds and keep out weeds).
Propagule Collection: We let the seeds fall on the weed fabric as the ripen. This is a very late season plant. We usually sut the plants back in October, thresh out whatever seed is left in them and clean the weed fabric using a leaf-blower in reverse (as a vacuum).
Propagule Processing: Seeds were cleaned using a small air screen machine.
Growing Area Preparation/
Annual Practices for Perennial Crops:		 Seeds were sown into cone-tainers filled with Sunshine#1 (a soil-less, peat-based media) amended with micro-nutrients (Micromax) and a slow-release fertilizer (Osmocote 14-14-14). Flats of cone-tainers were placed in a heated greenhouse. Seeds germinate best in hot temperatures. This is a late season plant, when greehouse temps were above 80 degrees, the seeds began to germinate.
Establishment Phase: Seeds germinated readily with no treatment (in a hot greenhouse).
