Germination Information

Pre-treatment: Seeds are placed in cold stratification. Seeds are also soaked in a 1:4 bleach/water solution for 1 to 3 hours, then leached overnight to remove any inhibitors and to allow full imbibition of seeds prior to sowing.

Establishment: Seeds are collected in late spring. E. nevadensis is found from Oregon and Nevada south to California and Arizona, and is common on dry hills and slopes mostly below 4500 ft elevation from Arizona and Utah to Owens Valley, California. The length of the establishment phase is 4 weeks.
