PASTURE SAGE:  Common throughout much of the Prairies, this species spreads by rhizomes under the soil to form colonies over time.  Growing to 120 cm in our plots, the silver-gray foliage with its distinctive smell makes a great backdrop to other flowering species.  Suitable for the true wildflower area, in a garden situation this species must be contained.  Seeds are very tiny and should be covered with just a light dusting of soil.  Can be direct seeded in late fall, early spring or started indoors after a 3-4 week moist stratification period.  Prefers a sunny site and poorer soils.   100 seeds.    NF721
