Best Plants for Bog/Wetland Filter

[MitchW]

Hi Everyone,
I am almost done building my pond, there is water in the pond... I am in the process of building the bog/wetland area, similar to what @addy1 has done.
I am located in Toronto, Canada.
Are there any recommendations on plants for a bog/wetland filter?
I found this list at Nelson Water Gardens.

I just planted and what lived is still in the bog. Currently water willow, obedient plant, marsh betony, yellow flag iris, lizard tail, creeping jenny, blue forget me not , some other iris, water mint, spider wort, lirope and others I am forgetting.

Thanks @addy1.
Do they over-winter well?

 

[addy1]

Yes they all die back freeze and come back even stronger

THE MINT Oh the mint is very aggressive but easy to remove

My favorites are:

Marsh Marigold

Great Blue Lobelia

Cardinal Flower.

The best bog plants are those that grow fast. When the spring comes along the water is rather nasty from being idle all winter. So the quicker a lot of plant mass gets growing the better the pond will be. This is a double edged sword as with growing fast also can mean it will take over under optimum conditions in only a couple years. Faster it grows the more nutrients the plant needs thus staving out algae

My water is just a bit murky after winter, within a few days after turning on the bog it clears right up. That is even without a lot of plants growing. When I flip it back on the plants are maybe 1-2 inches high and or just a bit of green showing.

Beautiful garden, JB. Thanks for this as well. those are also some of my favourites, I didn't know that they can grow in a bog.
