A Yew would have been fun to work with, but I think it might be outside the 'rules'. Per Wikipedia "Taxaceae is now generally included with all other conifers in the order Pinales."
Seems they are conifers. Regardless, I'll probably try to participate, but around here, nursery stock may also be pretty limited in March. April may be better, but at worst, I'll participate in a Summer round.
FYI / TMI:
This may have been confusing because a conifer is not a Family level distinction, as suggested by the OP. IIRC, A conifer is defined at the Division/Phylum level (depending on where/when you learned biological scientific classification
http://en.wikipedia.org/wiki/Biological_classification). Specifically, division/phylum Pinophyta, also known as Coniferophyta or Coniferae. At least, I think so.
