Good morning All...I'm a newbie to the pond scene but so far fingers crossed i've only had one or two issues that some knowledgeable people on here have helped me with to great success but now I've a question re my Nymphaea Pygmaea Rubra.. neither of them have flowered. I bought them bare rooted and planted them according to the instructions but although we've had lots of leave and they have full sun for more than 4+ hours a day we've not seen any signs of a flower...would anyone have any ideas why? Thank you in advance
