Special remarks H. longipes and its forms are highly variable in nature, so it's only natural a number of different morphs and clones are in cultivation.

  • H. 'Iwa Soules' (Japan/ M. Soules NR), also known as H. 'Iwa' is a cultivated clone, obtained by M. Soules from Japan in 1986. It is more correct to label this plant as H. longipes, obtained by Soules.
  • H. 'Steady On' (R. Lydell NR) = H. longipes selection
  • Ogon Iwa, the common name for the yellow form
  • Tochi Ogon Iwa, with intense yellow leaves, from the Tochigi Prefecture

Variegated sports of H. longipes occur in the wild, and are highly sought after in Japan.  They are extremely exclusive and expensive; the owners most of the time refuse to have them exported to the western world, to avoid these rarities end up in tissue culture, thus losing most of their (financial) value.
