Has anyone ever come across water marigold (Bidens beckii) or buttercup (Ranunculus longirostris)? I'd really like to add some to my tank but I can't find anywhere that sells it. They both have nice flowers, and marigold has some nice leaves that form above the water level that would look nice in my open top tank.

hi
i found some on ebay.
perhaps contact an online plant surplier if you don't find it for where you are.
hope this helped.

hey thanks.. which one did you find on ebay?? do you happen to have a link?

hi
yep here you go...................

don't forget i'm in England.
so i don't know if they would ship over sea.

That's a interesting post...I know these plants from the yard but would not have thought there's a 'underwater' version of them as well. And they thrive long term fully submerged willow?

Thanks for the links, but unfortunately they aren't the aquatic versions of marigold and buttercup that I am looking for. I would consider both of these as wetland, or semi-aquatic plants. The two that I would like are Ranunculus longirostris (common names include water buttercup and white water crowfoot) and Bidens beckii (commonly called water marigold). They look and grow similar to Myriophyllum species, and I've often been sent samples of them by people worried that they're Eurasian Watermilfoil.

I've attached a few photos of each, they both produce a nice tiny flower in mid to late summer, and the buttercup can smell quite nice.

The neat thing about B. beckii is that the flower spike will also create emergent, free-standing leaves...something not often seen in aquatic plants, at least around here!

The top two pics are R. longirostris and the bottom two are B. beckii. I'm guessing they aren't commonly cultivated, but I'm always keeping my eyes peeled as I'd love to try and get them to flower!

To answer your question Angel, the links posted probably wouldn't survive long fully submerged, but these two would since they're true aquatics.

Had you tried emailing sweetaquatics.com? I know Mary can get her hands on a lot of stuff, may take a lil while but she can get lots stuff.

no idea Angel sorry.

shame it's not the ones,but like Angel said perhaps a proper aquatic plant specialist would be able to get
exactly what you wanted.
good luck with the search.
:)

I've never bought anything from them, but I see the name on here constantly! I never saw it on her website but I'll send an email, thanks!
