I have one tropical lotus growing in a concrete pot. It has started putting out aerial leaves and I'm hoping it will bloom this year. I thought it died last year and pulled the pot and let it dry out. I went to use the pot for something else this spring and found 2 live tubers in it. I planted them and now the lotus is coming up much stronger than before. I never got any aerial leaves last year. I am putting a lot of fert spikes in, 2 or 3 a week and that may be the difference.
I bought the seeds online and half were pink and half white, I've no idea what this is so I'm really hoping to get a bloom.
