| Family Scientific Name: | Liliaceae | ||
|---|---|---|---|
| Family Common Name: | Lily Family | ||
| Scientific Name: | Lilium michiganense Farw. | ||
| Common Name: | Michigan lily | ||
| Species Code: | LIMI9 | ||
| General Distribution: | Of low moist, rich areas in full sunlight to light shade. River flood plains of rich deciduous woods. A very showy orange lily up to 5' in height. | ||
| 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 from June to September. Seed is a flat papery capsule and is harvested in September. | ||
| Propagule Processing: | Dry seeds for 1-2 weeks in open paper bags or open Rubbermaid-style bins. Seed is not cleaned. Once seeds have dried begin stratification. | ||
| Pre-Planting Treatments: | Stratification: mix the seeds with an equal amount of moist perlite or vermiculite. Put mixture into a Ziploc-style bag or a Rubbermaid-style container. Seal the container and proceed with 2-3 months of warm moist stratification at room temperature followed by 2-3 months cold moist stratification in a cool dry place. Cold store until 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 to allow for cooling. Container Type: grows best in 24 cell (2" diameter) 14"x8.5"x4" deep flats. Can be grown in virtually any plug size. 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 the 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 3 seeds in each cell. Cover the seeds with a thin amount of soil. Sow year-round due to low variable success rates. About 75% of our seeds germinated, but only 10% of those made it to plug maturity. |

| Establishment Phase: | From January until August 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. through Dec. the greenhouse thermostat is set at 55 degrees F. During this season ambient greenhouse temperatures may reach 75 degrees F during the day. Soil is kept consistently damp during germination. Water using a fine mist or light hose setting only. Newly planted trays are 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. The greenhouse holds plants at all stages of growth so the temperature setting stays the same for all plants at all stages of growth. Plant trays are moved 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 there is no longer frost at night, plants can be left directly outside. Plugs in this phase do not need to be watered as much as plugs in other stages. | ||
| Harvesting, Storage and Shipping: | In the Upper Peninsula, flats are transplanted into the field from late May to early October. Flats that are not planted in the summer remain in the greenhouse for another growing season. | ||
| Other Comments: | Very difficult to transplant and establish via seed or plug. | ||
