| Family Scientific Name: | Compositae | ||
|---|---|---|---|
| Family Common Name: | Aster Family | ||
| Scientific Name: | Aster pilosus Willd. | ||
| Common Name: | Frost aster | ||
| Species Code: | ASP12 | ||
| General Distribution: | On sandy and gravelly shores and beaches, interdunal flats and swales, limestone pavements, rarely in fens. Calciphile. Has spreading hairs on stems and leaves. The bracts and leaves around the flower often have spinulose tips. Basal rosettes of oblanceolate leaves present at flowering time. | ||
| Propagation Goal: | plants | ||
| Propagation Method: | seed | ||
| ProductType: | Container (plug) | ||
| Time To Grow: | 0 | ||
| Propagule Collection: | Seed is collected by hand from locally native plants within the eastern central Upper Peninsula. Flowers in August through September. Seed is an achene and is harvested October thru November. | ||
| Propagule Processing: | Dry seeds for 1-2 weeks in open paper bags or open Rubbermaid-style bins, shaking or turning seed heads. Seed is not cleaned. Once seeds have dried begin stratification. | ||
| Pre-Planting Treatments: | Stratification: Mix the seeds with an equal amount of either perlite or vermiculite in a sealable plastic bag or Rubbermaid-style container. Seal and put in a refrigerator or cold garage (35-42 degrees F) for 1-2 months. Cold store unti planted (up to 3 years). | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Propagation Environment: Greenhouse film is made of Standard U.V. 3HL Clear 6 mil (J.R. Johnson's Greenhouse Supply Inc.). Fans run continuously to circulate the air. Vents open during the summer months for cooling. Container Type: grows best in 24 cell (2" diameter) 14"x8.5"x4" deep flats. Sowing Media: Scotts Redi-earth Plug and Seedling Mix. Contains vermiculite, and sphagnum peat moss. Soil is sterile. Thoroughly moisten the soil with water, mixing in the water with a trowel. Cover the holes in the bottom/sides of the plug tray cells with newspaper so that the soil does not fall out. Fill cells with damp soil and press soil down with a spoon. Refill the cell plugs with soil to the top, this time not pressing it down. Water the soil in the plug cells again. Sow the seeds by hand at a rate of about 1 seed in each small cell and 2 seeds in each cell with a diameter greater than 2.5". Cover the seeds with a thin layer of soil or gently press the seeds into the dirt. Sow year-round due to unpredictable germination. |

| Establishment Phase: | From Jan. until Aug. the greenhouse thermostat is set at 65 degrees F both day and night. Ambient greenhouse temperatures may reach 100 degrees F during the day in the summer. From Sept. thru Dec. the thermostat is set at 55 degrees F. During this season ambient greenhouse temperatures may reach 75 degrees F during the day. The greenhouse holds plants at all stages of development so the temperature setting stays the same for all plants at all stages of growth. Soil is kept consistently damp during germination. Water using a fine mist or light hose setting only. Newly planted trays should be placed on the south side of the greenhouse. No artificial light is used. | ||
| Active Growth Phase: | The soil does not need to be consistently moist. Move trays to cooler north greenhouse tables. No fertilizers are used. | ||
| Hardening Phase: | In early-late spring, mature plants can be moved into a cold frame with a cover of material that diffuses sunlight to prevent scorching of the plants. When danger of frost has passed leave plants outside. Water less frequently. | ||
| Harvesting, Storage and Shipping: | In the Upper Peninsula, flats are planted from late May to early October. Flats that are not planted in the summer are left in the greenhouse for another season. | ||
| Other Comments: | Frequently found in disturbed or overgrazed prairies and pastures. Can be weedy. | ||
