I crossed Tribarrel Cacti & Water Plants,..expecting to get prickly pear cacti, per stratics webpage. Colors came out as expected, but when I ID'd the seeds with poppies dust, I got a distribution of 4 plants from each cross. None was the expected prickly pear. What's up? Change in gardening with recent publish? Bug? Bad poppies dust? Help me, Help me, oh, Wizards of the Soiled Trowel!
