Built a 300g pond with mini bog filter. Now thinking about landscaping it with mostly California natives.

Can anyone suggest plants? Can anyone suggest where to source these (either bought or legally collected)?

I知 thinking of some spike rush or common rush for my bog filter, maybe an iris (blue flag?). I知 not sure about submersed plants.

I知 very new to all this, but found this list https://calscape.org/loc-California/...c60a2844a4f59f
