    Hi y'all!

    Just had a delivery of Tropica's Prosperpinaca Palustris 'Cuba'. I had thought from looking at the images on their website that it was a stem plant.
    What arrived is a very small group of plants with the roots grown in together. I've broke it up into some small bunches and planted it a couple of inches apart.
    Anyone had any experience of this? Do I need to thin them out or let them grow on a bit first?

    Well, it is a stem plant. But I have never seen the emers form. I would suggest to give the individual stems some space, just like other plants.
    And just something I encountered previously: It was quite hard for me to get more stems from this plant. The old big tops were doing fine, but after trimming the new sprouts on the old stem rotted away or didn't grow in the first place. I had the most succes by floating of the stems at the surface.

    greets,

    We call it mermaid for good, reason, it's a real weed in the SE USA.

    It looks more like Myriophyllum in natural systems is a common road side ditch weed.
    Emergent form is very prolific, producing large amounts of seeds.
    You might have issues growing it, but it's far from a sensitive species.

    Does better in winter than summer due to slower grow rates, but it will grow all year long.

    Regards,

    Hmm, thanks.

    I'll keep an eye on it and take it out if it gets too invasive. I take it that it doesn't seed when submersed?

    According to Tropica, this is a Cuban derivative that grows to a medium height (< 40cm) It looks nice in their article (Tropica Prosperpinaca Palustris), turning a nice deep copper. Oh well, I can only give it a try.

    I doubt there's much difference between this one and the Cuban variety.

    I tried unsuccessfully to grow Proserpinaca palustris. So, I gave it up. My tank water temperature was about 79F the whole time, and I have since heard that a lower water temperature would work better. If I ever lose my mind and try it again I will lower my water temp to about 72F.
