      Based on 7 reviews

      This thing is fabulous! Great growth on it and a bunch of roots already looking to anchor into the substrate when received. Super happy I got this plant. It looks so good.

      Crinum Calamistratum

      Received this plant as part of a larger order. All the plants in order arrived in a timely manner and all appear very healthy. The Crinum was of a good size and appears very robust with dark green leaves. I was especially pleased with this plant that is going into an angelfish/tetra tank. I am so pleased with this plant that I will most likely order at least one more for another tank I am in process of setting up. Thanks to the staff at APF for quick delivery of good products!

      Crinum Calamistratrum

      This product was much more than I expected! It came healthy and large. A great deal for the price!

      Love these!!

      Took a chance on these during the holiday sale. So glad I did. They are super healthy with lots of baby leaves coming in.

      Gorgeous little onion!

      Crinum Calamistratum is an African water onion. When I first decided to setup a tank a few years ago, this was the one plant I was most excited about. It was out of stock at the only plant shop I knew of and I didn't take the time to look for other aquatic plant retailers. Fast forward a few years, I finally took the search engine plunge. I found APF very easily and lo, they had this curly little cutie in stock! So yeah, it took a few years for me to get this, my dream aquarium plant, and it's so much more impressive in person!
      The Crinum arrived in beautiful condition: all the leaves were intact and I did not experience any melt at all. This little beauty is thriving in my Dwarf Puffer tank, they love playing with the swirly fronds! If you're looking for an easy-care plant for a low tech setup with show-stopping beauty, this is it.

      Cute little plant

      My cc came in a little ziplock and I immediately put him in my tank. Substrate is Amazonia light. It didn’t die but didn’t make a lot of progress either. It is kind of there couple of tentacles seem to have grown a little. I think this plant is super slow to get established. It was a little cooked when it came but that is because it’s summer and I live in hot Midwest. I think it will come around. It sure is cute plant. It gets good circulation, light and nutrition so it’s just matter of time.
