Despite what you may read Dichorisandra thyrsiflora is not that easy to propagate by division of tubers, as these do not sprout. However division of clumps and stem cuttings are both satisfactory.


  • Look for an established clump and try to carefully separate some of the healthy growing sections.
  • Take care to have a good part of the root system attached to each division.
  • Best to keep divisions large with 4 – 5 stems in a division.
  • Prune back the stems by 50 % to reduce stress, but make sure you still have some foliage on them

Stem Cuttings

An easier method is to propagate from stem cuttings. Simply find a long healthy stem.

  • You will notice nodes on the stem.
  • Cut the stem into sections with 4 – 5 nodes on each section.
  • Simply plant them in a free draining potting soil.
  • Try to keep these cuttings humid until signs of new growth are evident.
