Germination Information

Pre-treatment: Extended cold, moist stratification. 90 days of cold, moist stratification resulted in 33% emergence. Containers sown in November and left outside under cool, fluctuating spring temperatures achieved 97% emergence.

Establishment: Seeds were covered in all trials. The effects of light on germination were not explored. Seedlings which germinated in the greenhouse thrived in the constant warmth, so it is likely the longer stratification time and not the cool, fluctuating temperature was the factor in the increased germination. Seed is collected in early July when the inflorescence is dry and the seeds are grayish-brown in color.
