1:E. affinis 古紫 x E. shaviana 沙维娜 Black Prince 黑王子
黑王子这个大普货也有来历不明的问题。
ICN原文:
Parentage : E. affinis x E. shaviana
Created by Frank Reinelt, Capitola, California
Description by Abbey Garden (in "Abbey Garden Plant Distribution List") :
"Echeveria 'Black Prince: this is the first offering of this appealing new cultivar developed by Frank Reinelt of Capitola, California. the seed parent is Echeveria shaviana and the pollen parent is E. affinis. E. affinis, the "black" Echeveria, gives the new plant its color, and E. shaviana gives the plant its delicacy. Rather than black, the 'Black Prince' is actually more of a dark lavender brown. The rosettes are up to 3 inches in diameter; the leaves are quite thin and at first triangular, becoming rather spatulate, to 23 mm wide, tip acuminate, the very point is hyaline yellow."
Note :
Obviously, the plants we have with the name 'Black Prince' do not well match the above description, they are not "dark lavender brown", the leaves are neither thin nor spatulate and the very point is not hyaline yellow.
Conclusion : The parentage E. affinis x E. shaviana is not correct for the plant today called E. 'Black Prince'.
As E. affinis is only "slowly proliferous" and E. shaviana is also only "sparsely branching" it may well be possible that this hybrid has got lost to cultivation and the name been attached to other "black" echeverias - what would explain why 'Black Prince' is a very variable hybrid.
