I have been hybridizing Haworthia for nearly 20 years. Most of my hybrids are multigenerational complex hybrids created from carefully selected parental stock. I breed to intensify and combine leaf and window coloration, leaf texture and leaf shape traits.
Leaf coloration is influenced by the interaction of the pigmentation of the leaf and the coloration and the windows. The windows can be clear or can have spots which vary in size. In hybrids the spotting often turns the entre window opaque. I strive for obtaining reds, pink, purple, orange, dusky gray-blue and more recently phosphorescent green.
Leaf texture can be smooth or bumpy or bristly. In some of my hybrids I get red colored spines and bumps.
Haworthia can have many variations in leaf shape. I use plants like truncata in my breeding to introduce variations in leaf shape.
In 2005 I started numbering my crosses to keep track of them. So my numbers are labeled as PP#. For each PP cross there will be multiple siblings, all genetically unique individuals that will express slightly different traits. Therefore you will be obtaining a one-of-a-kind plant that no one else has. I hope you take good care of it. The seedlings will change as the age and pigmentation will usually intensify over time.
