Over the past 4-6 weeks my Amazon Sword (Echinodorus Paniculatus ?) has sent four shoots outward and upward, 18-24". At first I thought this was some type of flowering but it appears that the shoots are beginning to sprout leaves and more shoots. I have had this plant in the tank for about a year and a half and have never seen this before. Is this normal? TIA. John Haydt
