How to Propagate Pennantia?
Pennantia can be propagated by seed sowing or semi-hardwood cuttings. Successful propagation depends on factors such as adequate light, warmth (temperatures around 20°C), and well-draining soil. Special considerations include providing humidity for cuttings and stratification for seeds if they're dormant. This plant has a moderate difficulty level for propagation due to its specific needs. To propagate from cuttings: (1) take semi-hardwood segments in late summer, (2) dip the cut end into rooting hormone, (3) plant in a mixture of peat and perlite, (4) keep moist and under partial shade, (5) transplant once rooted. For seeds: (1) sow fresh seeds in autumn or stratify if necessary, (2) cover lightly with soil, (3) keep moist and in a warm, bright location, (4) transplant seedlings once they have several true leaves.
