Germination Information

Pre-treatment: Seeds are pretreated with a 3 to 5 minute Physan fungicide soak or a 5 minute 1% bleach solution to surface sterilize seed coats. Seeds are also imbibed in distilled water for 24 hours and cold, moist stratified at 40 F for up to 4 weeks. A smoke treatment using 'Instant Smoke Plus Seed Primer' is also applied by soaking seeds for 24 hours in primer solution.

Establishment: Catalina tarweed is endemic to the Channel islands where it inhabits dry rocky sea cliffs, rocky bluffs and valley foothills and grasslands. Germination percentages have typically been low regardless of treatment.
