Family Scientific Name: Malvaceae
Family Common Name: Mallow family
Scientific Name: Sidalcea cusickii Piper
Common Name: Cusick's checker-mallow
Species Code: SICU
Ecotype: Seeds were collected in Lane Co. near Eugene.
Propagation Goal: plants
Propagation Method: seed
ProductType: Container (plug)
Time To Grow: 0
Pre-Planting Treatments: Seeds were scarified useing a small oat dehuller lined with 320 grit sandpaper, then 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). The flats of cone-tainers were covered with poly-ethylene bags and placed in a walk-in cooler (35-40 degrees) for 45 or 90 days. Some flats were placed in a greenhouse as a "control"
Growing Area Preparation/
Annual Practices for Perennial Crops:		 Flats were removed from the cooler after 90 days and placed in a greenhouse set at moderate temperatures (70 degrees days/50 degrees nights).
Other Comments: No difference was noted between the stratified and non-stratified seeds. Continued to germinate all year long. Scarification helps inital germination, but will only raise the inital germination to about 50% (depending on the seed lot).
