Thanks guys. I couldn't figure out why the German seed bank had only 1 of 4 diff C. eximium seed packs marked 'Ulupica' and not the C. cardenasii. My first year growing both. Only 2 of 9 C. cardenasii sprouted and one seedling probably won't have enough vigor to shed the seed cap. Only 6 seeds left so might end up with a single plant. JohnT
