I was at Lowes the other day, and they had Egyptian Papyrus, but no real info on it.
I researched it, its a reed, grows in very moist or boggy conditions, its much like bamboo, rhizomes, grows very fast, tolerates heat, and its beautiful it has a frilly top that looks almost like an air plant. I bought one, and have it submerged about 4 inches from the top in my pond. But, its taking up a lot of space, and its not really secured, it could tip, I plan on putting it in a much larger planter and keeping it near the pond and submerged.
I'll get a pic of it tomorrow, its a great plant, never seen it in AZ.
