Plant Profile

 
Didiplis diandra- Blood stargrass, waterhedge

 

Native to North America. This plant has very thin stems and leaves and does not like alkaline water. Under bright light with nitrate and iron addition, the leaf tips become red and elongated.

 

It is described by some people as a difficult plant, but I have found it fairly easy as long as you have bright light, not too hard water, and feed it regularly. Do not allow algae to collect on this plant. If your tank becomes besieged with Blue Green Algae, use an anti biotic immediately to kill it. If you let BGA cover this plant it is not likely the plant will survive. I first suspected this plant may not tolerate high temps well, but it does grow extensively in Florida and other southern states that have very hot summers.

 

It reaches a height of 10 to 15" and looks very attractive planted in groups. It's needle like clusters of opposing leaves give a nice contrast in shape to more broad shaped plants, and if you get your plants to take on the red coloring it is particularly attractive.
