Can Creeping Jenny be planted in a pond?

I'm no expert on this but I think Creeping Jenny will tolerate bog conditions but not underwater planting. It is fairly invasive in all it's planting situations so go careful.

Yes your right Maple would much prefer trailing over edge of pond to being immersed in it .At 8" depth would need to float on surface try water hawthorn or water forget -me - not.If you havent already.
