So I am interested to know what everyones oldest plant species are in their tank? Took me a while to think but came down to about 3. First, being an Amazon Sword that has been in my tank for 4 yrs. Second, Bacopa Austeralis which I was givin free from the pet store because it look so bad. I brought it back to life after 3 1/2 yrs and have probably made 100 dollars worth of store trade from this plant alone. Gotta love tade ins and a tank that pays for itself. And third, my crypts of course. Both red and green wendtiis which have been a struggle for about 5 yrs. Still waiting to see the pottential that they once were. So what are yours?
