Family Scientific Name: Poaceae
Scientific Name: Koeleria cristata
Common Name: June Grass
Species Code: KOCR
Ecotype: Colorado, Beaver Meadow Picnic (98-032s, 98-065s), Moraine Park (98-066s), McGraw Ranch (98-067s), Hollowell Park (98-068s), Twin Sisters (98-069s), Upper Beaver Meadows (98-070s)
Propagation Goal: seeds
Propagation Method: seed
ProductType: Propagules (seeds, cuttings, poles, etc.)
Time To Grow: 0
Propagule Collection: Seed cleaning technique: Seed stripped by hand from panicle. Best to use tweezers to tease seeds from inflorescence as many remain after hand stripping. Many non-viable, empty seeds. Seeds are soft, so sieve is not recommended. Seed is mixed with large quantities of miscellaneous plant material after cleaning.

Beaver Meadow Picnic (98-032s, 98-065s) collected on 8/25/98; Moraine Park (98-066s) collected on 8/24/98; McGraw Ranch (98-067s) collected on 9/3/98; Hollowell Park (98-068s) collected on 8/9/98; Twin Sisters (98-069s) collected on 8/27/98; Upper Beaver Meadows (98-070s) collected on 8/16/98; MPCG collected on 8/14/98.
Pre-Planting Treatments: Seed Treatment: None.
Growing Area Preparation/
Annual Practices for Perennial Crops:		 Propagation Environment:Greenhouse, 65-70§F day/55§F night. Propagated under tent with misters set 8 am-8 pm, with 10 sec/15 min watering intervals. One week after germination, seedlings were moved to mister area without tent.

Germination media: Fafard Germinating Mix (superfine).

Growing media: Fafard Growing Mix 2.
Establishment Phase: Sowing/planting technique: Manually sown on 4x4 or 12x12 flat. Recommend sowing in small pots for ease of divisions later. Surface sown as light is required for germination. Use lots of seed material as only a few viable seeds are present, this varies greatly by site.

Time to germination: Variable 5-10 days.

Establishment Phase: Slow and uneven.

Time to potting: 1 month.

Beaver Meadow Picnic (98-032s, 98-065s) sowed 11/3/98; Moraine Park (98-066s) sowed 11/12/98; McGraw Ranch (98-067s)sowed 11/12/98; Hollowell Park (98-068s)sowed 11/12/98; Twin Sisters (98-069s)sowed 11/12/98; Upper Beaver Meadows (98-070s) sowed 11/12/98; MPCG sowed 11/23/98.
Harvesting, Storage and Shipping: Seed storage condition: Seed stored in the greenhouse.
