Yes. You want to make the horizontal polygon at the largest extension
of the leaf canopy. This means the chance that in your view the
horizontal poly extends over the other two polygons is lowest.

BTW, I recommend setting the origin to the place where the stem goes
into the earth.

No - if you do not look directly from above, it will look very bad.
Say the leaf canopy is a sphere (two polys with circular mask
textures) and the horizontal poly is a circular disc as well. When
looking with a pitch of say 20 degrees down onto it, you will see the
"sphere" above and a ellipse below the "shere".
