I have Proserpinaca palustris: http://www.tropica.com/productcard.asp?id=037C My picture: http://194.236.255.117/lkpakvarie/defdac/gallery/310litres/palustris_small.j pg from http://www.akvarie.net/defdac/ It grows medium fast under adequate CO2 and PMDD-dosing and is a real eye catcher. I would not say this is a slow grower. // Daniel Larsson
