The above propagation data sourced from Claude AI
Pre-treatment: Seeds were placed on moist blotter paper in petri dishes, sealed inside closeable plastic bags to reduce desiccation, and placed in a -2øC germinator for two weeks, then held at +2øC. For larger production, seeds were dusted with Captanr fungicide powder and stirred into moist peat moss in closeable plastic bags, and placed in a +2øC germinator.
Establishment: The length of the establishment phase is possibly longer than one year. The white flowers bloom in late May to mid-June. The fruit is mature when it turns brown and dehisces readily. Seed was collected in late June to mid-July, approximately four to six weeks after flowering.
