That is great news, indeed!  I would love to see those tets bloom.  When
you say the foliage is larger...do you mean wider, thicker, or taller, or
all of the above?

It looks like I'm going to have to wait until December before I get a chance
at some of those tetraploid seeds through SIGNA.  I presume other
tetraploid species are listed from time to time?   Fulva, brevicaulis,
cristata, etc.?
