Hi Solo,

I've grown most of the above Alc's, but have not yet had them all come into flower. Alc regina is a bit of a mystery plant, & the current thinking is that it actually keys out to be Alc edmundoi. However, the plant we have here that has been tagged as Alc regina seems to be a larger variety of Alc geniculata.

All of the plants you mention will produce grass pups, with extensa, nahoumii & geniculata also producing normal pups some time after the mother plant flowers.

I do have a few clones of Alc imperialis x vinicolor, but none have flowered as yet. I've collected a few grass pups from them, & I do hope this hybrid follows the pattern of vinicolor in producing normal pups after flowering.

Cheers, Andrew.
