Growing tips
* Sometimes it can be difficult to see what side of
   the bulb rhizome or tuber is up or down.
   A good way to solve this problem is to plant them
   side ways.

* To get more plants from a rhizome, just
break it
   into smaller pieces.

* Check for synonymous, as many species names
   are changed. For instance;
   O. Melanostica is syn. with O.  purpurea  “Ken Aslet”
 
* Keep your plants healthy, remove dry leaves
  throughout the growing season.
  It gives air between the plant and can keep pest away.
