Family Scientific Name: Geraniaceae
Scientific Name: Geranium
Common Name: Geranium
Species Code: GERAN
Ecotype: Colorado, Sprague Lake (98-022s), Alluvial Fan (98-111s), McGraw Ranch (98-110s, 98-188s), Twin Sisters (98-152s)
Propagation Goal: seeds
Propagation Method: seed
ProductType: Propagules (seeds, cuttings, poles, etc.)
Time To Grow: 0
Propagule Collection: Seed cleaning technique: Seeds removed from seed head.
Propagule Processing: Germination: Sprague Lake (98-022s) = 0%.
Pre-Planting Treatments: Seed treatments: Seeds require scarification.
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: Surface sown in 36 pk, with 1 seed/slot. Pressed seeds firmly into soil.

Establishment Phase: Germination and initial growth rapid.

Sprague Lake (98-022s) sowed 10/27/98: Alluvial Fan (98-111s) sowed 12/4/98; McGraw Ranch (98-110s, 98-188s) sowed 12/4/98.
Harvesting, Storage and Shipping: Seed storage condition: Seed stored in the greenhouse.
Other Comments: Comments: Seeds require scarification. Soaking for 24 hours following scarification may enhance germination. Sprague Lake seeds (with no germination) were not scarified.
