The above propagation data sourced from Claude AI

Pre-treatment: Seeds were plated on 1.5% agar in petri dishes and incubated in growth chambers at various temperature treatments. However, another protocol suggests no treatment is necessary.

Establishment: Seeds germinated to 100% in most temperature treatments, with the exception of late-spring conditions (68°F/50°F) where germination was 60%. Another protocol reported 72% germination without any pre-treatment. Seeds were collected when the capsules were dry and the seed was in the hard dough stage.
