    Healthy plants

    Healthy and good size. Out all the plants that I put in my aquarium, this one melted to nothing and hasn't come back. Not the seller fault. The shock of different aquarium conditions can cause plants to melt.

    Nice but small

    Received two small stems. However, they were very nice looking with huge roots.

    A little color, Please

    And this was added for color - other than green - in my planted aquarium. I'm a newbie to plants and so far everything is perfect. This was another great addition.

    The plant arrived in great shape! I was very pleased to see how healthy the plant was. After soaking it in room temperature for over 24 hours, I planted it in my aquarium. I hope it likes it’s new home.

    Love the Purple!!

    Posted by Micah A Alden on 13 Sep 2021

    These came in great condition despite the delay from FedEx. The one piece I was able to take the top off and it rooted itself within days and all pieces are really healthy and growing in quickly. Great mid ground plant for my tank.

    Cardinal Plant

    Simply beautiful! Cardinal came in healthy and with vibrant colors. Didn't know which way to plant in substrate so stretched it out a bit and put a lead spike to hold in place and it's roots are going down into the substrate. Colors have faded a little but I don't have enough light so I'll be cranking up the light slowly. Just happy!
