i know that all plants in north america are female as i was searching for a male plant. is there any or does anyone have any for sale or know of a source where i can get this?
Are you reffering to Myriophllum aquaticum. ?? I wasn't aware they occured in M?F . In any event if the purpose is to reproduce them , just plant in a wet place and jump back lol They are a "noxious ' weed in about 15 states lol. Have never heard of anyone growing from seed. If in a warm climate be VERY careful where you plant. gary
