Family Scientific Name: Polygonaceae
Scientific Name: Eriogonum umbellatum
Common Name: Sulphur flower
Species Code: ERUM
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 by crushing "flowers" and removing seed with tweezers.


MPCG (98-049s) collected on 9/9/98; MPCG (98-073s) collected on 9/9/98; Twin Sisters (98-048s) collected on 8/27/98; Twin Sisters (98-075s) collected on 8/27/98; Sprague Lake (98-010s) collected on 9/16/98.
Propagule Processing: Germination: All of the following locations low percentage:
MPCG (98-049s, 98-073s); Twin Sisters (98-048s, 98-075s); Sprague Lake (98-010s).
Pre-Planting Treatments: Seed treatments: None, 30 day cold moist.
Growing Area Preparation/
Annual Practices for Perennial Crops:		 Propagation Environment: Greenhouse, 65-70§F day/55§F night. Propagated on heat pad (set at 70§F) 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 sowed in seed flat 2-3/slot, lightly covered with germinating mix.

Time to germination: 6 days.

Establishment Phase: Germination uneven.

Time to potting: 1 month.


MPCG (98-049s) sowed 12/4/98; MPCG (98-073s) sowed 11/12/98; Twin Sisters (98-048s) sowed 11/12/98; Twin Sisters (98-075s) sowed 12/4/98; Sprague Lake (98-010s) sowed 10/27/98.
Harvesting, Storage and Shipping: Seed storage condition: Seed stored in the greenhouse.
Other Comments: Comments: 30 day cold, moist treatment did not seem to enhance germination.
