Hi everybody,

I am not convinced by the hybrid origin of P. 'enigma'[Edit: corrected to read, P. 'Enigma', cultivar names are capitalized and in normal letter, not italics or underlined] (a very nice cultivar I am really happy to grow)

I believe that this is a green form of this species like we may found some in P. potosiensis for exemple even if its flower is normal coloured.

If I can share my feeling for the YuccaDo complex, I can say that '1713' is a P. esseriana.

'1716' and '1718' are P. potosiensis
