Family Scientific Name: Compositae
Family Common Name: Aster family
Scientific Name: Coreopsis lanceolata L.
Common Name: Lanceleaf coreopsis/Tickseed
Species Code: CORLAN
General Distribution: Full sun to light shade. Dry to somewhat moist sites. Sandy to rocky soils. Shorelines, alvar, openings. Bright yellow flowers. Plant height 8" to 3'. Foliage luxuriant.
Propagation Goal: plants
Propagation Method: seed
ProductType: Container (plug)
Time To Grow: 0
Propagule Collection: Seed is collected by hand from locally native plants in the eastern central Upper Peninsula. Flowers from early July through September. Seed is a small black achene and is harvested throughout the summer, the majority in August-September.
Propagule Processing: Ripe seed can be lightly tapped from the seed head. An individual flower's seed varies in time of ripening so one flower's seed could be harvested several times. Seed is not cleaned. Dry seeds or 1-2 weeks in open paper bags or open Rubbermaid-style bins, shaking or turning seed. Once seeds have dried, store in sealed Ziploc-style bags or Rubbermaid-style bins. Cold store until planted (up to 3 years).
Pre-Planting Treatments: None are used. Seed readily germinates.
Growing Area Preparation/
Annual Practices for Perennial Crops:		 Propagation Environment: Greenhouse made of standard U.V. 3HL Clear 6 mil from (J.R. Johnson's Greehouse Supply Inc.). Fans run continuously to circulate the air. Vents open during the summer months for cooling. Container Type: Grows best in deep cell plug trays; 100 cell (1"-1/2" diameter), 18"x12"x6.5" deep. Growing Media: Scotts Redi-earth Plug and Seedling Mix. Contains vermiculite, and sphagnum peat moss. Soil is sterile.
Add enough water to the soil to saturate. Mix soil with a trowel. Cover the holes in the bottom/sides of the plug tray cells withnewspaper, as the soil will fall through. Fill cells with damp soil and press down with a spoon. Refill the cell plugs with soil to the top, this time not pressing it down. Thoroughly moisten soil in the plug cells, but do not saturate. Sow seeds by hand at a rate of about 3 seeds in each cell. Cover the seeds with a thin layer of soil or gently press the seeds into the dirt. Sow February until late July.
Establishment Phase: From Jan. thru 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 growth so the temperature setting stays the same for all plants at all stages of growth. Soil is kept consistenly 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. 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 diffused 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 out-planted from late May to early October. Flats that are not planted in the summer remain in the greenhouse for another season. Transplant if they outgrow initial containers.
Other Comments: Attracts bees and butterflies. Handles frost and drought well. Long bloom period. Provides luxuriant cover in ashort amount of time. Reseeds very well in bare soil. Previous year's growth may be gently removed.
