Propagation & Germination

Stratification:
Cold/moist stratification required — 90–120 days
Germination Time:
30–180 days
Notes:
Seeds require removal of fleshy aril before stratification. Germination can be erratic and may take up to a year.

The above propagation data sourced from Claude AI

Pre-treatment: Cold-moist stratification for 30 days at 1–5°C (34–41°F).; then Cold-moist stratification for 60 days.

Notes: Seeds may require light for germination.

ORGHPS Germination Guide: Sow immediately, Either the viability of these seeds is short or the species propagates best with fresh seed. Stored seed might be coaxed into germination with temperature cycling and patience. Use repeated cycles of 4°C, then 20°C for 3 months each. Germination is very prolonged. * remove pulpy coat with detergent washes; germination unlikely if dried by just 20%, store seeds @ 4°C
