HOLD THE PRESS!!! You want the rhizomes NOT the tops. :mrgreen:
Treat the M. augustifolia exactly as you would with glosso: plant each leaflet or pair of leaflets WITH the rhizome every .5-1" apart. Don't bury it too deeply because the submerse leaves are very short and small: not unlike glosso. Once you notice new leaves, then cut the tall emergent leaves off. Within a matter of weeks under good conditions, you'll have a dense carpet.
