Re: Eriocaulon

Where did you read that this species is an annual? The Eriocaulon that I 
am familiar with is an evergreen (Eriocaulon septangulare). The seeds are 
fairly easy to germinate. Here in Canada they need a cold treatment and 
then they can be sown in trays in a fertile sand substrate (containing 
some soil). The plant may be difficult to culture as in nature they are 
found in oligotrophic, acidic lakes with extremely low DIC levels ... in 
fact they get their CO2 from the sediment through their roots ... I would 
think that with this plant CO2 injection would be essential. They are 
also amphibious and need fairly high light levels.
