Hi -

I'm new to tank plants but I'm very experienced with terrestrial gardening. I was very surprised to see Lysimachia nummularia 'Aurea' at my local pet store as an aquarium plant since I am so used to seeing it in my own garden.

I know that there are a number of primarily terrestrial plants sold as aquatic plants that last a while but ultimately fail. Is Lysimachia one of these, or have any of you had enough long term success with it to recommend it?

And if so, can I just yank some out of my garden for my tank? (Pesticides are not an issue.)

Thanks!

It seems to work totally immersed based on several online databases I've checked. I've been looking for it in SnS… maybe I should have gone to Lowe's. Lol.

I would suspect the leaves of a terrestrially grown plant would melt after immersion. I'm new to this, so take it with a grain of salt.

It will do just fine. I found some plants of the normal color form in my driveway as a weed and grew them successfully for quite a while. As an introduced plant, you will often see it growing along pond edges, sometimes with the also introduced Myosotis scorpioides (forget-me-not), which likewise does well under water.

I have done exactly that... taken some L.n. from a sunny spot in my backyard and submerged it in my tanks. It changes its shape and ends up looking similar to a large leaved Bacopa, with brighter green leaves.

It looks nice, but is a rather fast grower.

Never heard about Myosotis growing submerged, something to look into.
