Already thought of something.. 🙂 I replaced a floater, the one behind the flower bud, now the stem of this floater is in front of it and pushing the flower bud back. Now it will pop behind the filter outlet. Aesthetically not the best place above the tank, but i don't want to take any chances, comming this far. Actualy no idea when it will open up and how long this flower will live in this tank and if the stem keeps growing as it does for the floating leaves. The leaves stem grows on pretty long time even after the leaf already is floating.
It's my first time, in the pond i never took notice to this, just took it all for granted.
