Wednesday Poll: Dreaming the Impossible Plant

Last week, I planted some stuff that I've been wanting to try for a long time.  I'm not completely sure why I hadn't done it before.  I kept thinking there would be more time, or more space, or better conditions if I just put it off.  I had been going on that way for awhile when--not to rip off the movie title, but--one morning I just kind of woke up and thought, "Ya know, what if this is as good as it gets?"

Later that day, I ordered one Passiflora 'Incense' and two 'Sterling' hops rhizomes.

So, for this week's poll:

What's something you've wanted to plant and haven't?  Or, if you prefer, what's something you've always wanted to do and haven't?  For either question--what are you waiting for?

Comment and discuss.
