In Phragmites australis, detached vegetative fragments of culms and rhizomes can support local regeneration after disturbance and spread populations over considerable distances when transported with water, soil and other means. We tested the effect of phylogeographic group, plant part (culm, rhizome), environment (water, surface, buried), ploidy and genome size on regeneration. Regeneration was better in fragments placed in water than in those buried and on the sand surface. Phylogeographic group interacted with plant part – culms of the North American invasive populations regenerated better than those of North American natives. Our results point to a great regeneration ability of culm fragments, which can cope with a wide range of environmental conditions and grow rapidly to produce new plants. We suggest this played an important role in spreading the invasive populations in North America.
