poison ivy normally has 3 leaves (or leaflets) it can also have 5 or

I was thinking about this discussion the other day when I was out in
the yard. Just thinking about the way nature tends to work, it would
be more of a surprise if poison ivy always had 3 leaflets and never 5.
Think about how white clover had 3 leaflets, almost always, but then
there is that occasional 4 leaf clover in the mix.

Whoa, freaky...I was out yesterday planting some ferns and was
reflecting on this and thinking about 3 and 4 leaf clovers too...wow, an
m-field event (http://en.wikipedia.org/wiki/Morphogenetic_field), well
maybe not, but a coincidence none the less.
