Family Scientific Name: Malvaceae
Family Common Name: Mallow family
Scientific Name: Sidalcea campestris Greene
Common Name: meadow checkermallow
Species Code: SICA2
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 using a small oat dehuller lined with 320 gritsandpaper, seeds were then 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). Two flats of cone-tainers were covered with poly-ethylene bags and placed in a walk-in cooler (35-40 degrees). One was removed after 45 days the other was reomved after 90 days. One was left in a greenhouse as a "control".
Growing Area Preparation/
Annual Practices for Perennial Crops:		 Flats were removed from the cooler and placed in a greenhouse set at moderate temperatures (70 degrees days/50 degrees nights).
Other Comments: No difference in germination was noted between stratified and non-stratified seeds. Seeds continued to germinate all year. Scarification helps improve intial germination (from 20% to 50%. Even with scarification, seeds will continue to germinate over a long time period.
