This is all conjecture, Amy..Hope there is someone out there with THE
answer. If I'm correct about the butterfly weed, it may have something to
do with determinate vs. indeterminate growth habit, although even
determinate plants (like many annuals) can be fooled into rebloom. But I'm
always suspicious of plants that grow from tubers or rhizomes..For example,
if you deadhead your Bearded Iris, most of them don't have the capability
of rebloom (although a few also put on a fall flush).

I dragged out the ol' Webster's Unabridged..Senescence derives from L.
_senescere_, to grow old; from _senex_, old. And senile from L. _senilis_,
of or pertaining to an old man  :-)  Guess we're safe!
