  1. I want to know if you can grow Celosia Flamingo Feather Plants from cuttings. A nice piece broke off accidentally
    from my young plant.

  2. I have rooted cuttings of plumed celosia with good success. I did 5 cuttings in water in a sun room and all rooted. They sent out a long, single root and then feeder roots came later. These cuttings rooted anywhere from 2 to 4 weeks. Three rooted in about 2 weeks and the last 2 took about 4 weeks. Stems were healthy throughout the rooting process.

    I also tried 5 cuttings in sand. They also took about the same time to root but I had them outside where they got shade during the hottest part of the day. I kept the sand moist by setting the pot in a pie plate and put a milk jug over the top to hold humidity. On some days when there was intense heat, I watered the pot. I checked 2 of the cuttings today and they had roots and in more abundance than the cuttings in water. I will pot them up tomorrow.

    From my experience, they are easy rooters and I did not use any rooting aid. I used side shoots from the ‘mother’ plant about 4 inches long. Pinched off any buds and took off the bottom leaves leaving only about 3 or 4. The cuttings with the 4 leaves seemed to have the better root system.

  3. I am looking forward to growing this celosia in a pot this winter. It is very pretty. Should I pay attention to the size of the pot and the plant. are they easy to transplant?

  4. I have had 3 of them in my dart frog vivarium for the last year and a 1/2 in their still growing beautiful with the heat and humidity around 83 degrees
