erm.. i got the crypts off amy in wellington (dave&amy on here), the pygmy chain sword of vinson massif, tiger lotus from someone on here selling it at the time - i forget who, indian fern off someone in auckland.
the other plants, i ordered in through animates here, as i can order them in and take the ones I like
just bear in mind, that most plants with the exception of the rotala's are grown emersed, unless otherwise stated, so youhave to wait for them to re grow submersed.
eg- the sag. subulata comes only about 4 cm high and in small bunches, but in a few months it was more than 40 - 50 cm high in some places, and spreads like wild fire.
ps- i never gravel vacced the substrate, so that helped too.
