I didn't even know the lotus represented buddhism... and I was raised in a buddhist family my whole life! So anyway, now I'm very interested and have some questions. I did some research and it stated that they are best grown in pots to control their invasiveness and to overwinter. So how exactly do you place the pot in the pond? Won't it move around and float around if you just simply put it in the pond? Is there a stabilizer? And is overwintering really necessary if the pond won't freeze? I'm in zone 7 and yes water does freeze but I'll use a heater or something. Last question. How many flowers can I expect in one pot?
