The planet Uranus rotates on an axis that is tipped about 90 degrees to the ecliptic.

Probably the most significant effect would be that we would experience a total solar eclipse once every 28 days (or so) if the moon's orbital plane were exactly the same as the plane of the ecliptic.
Solar eclipses would be much more frequent
The planet Uranus rotates on an axis that is tipped about 90 degrees to the ecliptic.
Since Pluto, with an inclination of about 17.15 degrees, has been relegated to minor-planet status, the honor passes to Venus with an orbital inclination of approximately 3.39 degrees. See http://www.nineplanets.org/data.html
All planets lie in the plane of their orbit, but most spin on an that is nearly (many have tilted axes of spin) perpendicular to that plane. The one exception is the planet Uranus which has its axis of spin lying very close to its orbital plane.

Different planets, including Earth are tipped over. Neptune is by about 29.6°, which is slightly more than Earth. The planet that is most tipped over is Uranus at about 97.86°.
The reverse of the standard rotation, i.e. in the opposite direction of the orbital motion, is called retrograde. This term is most aptly applied to Venus, which rotates east-to-west (clockwise) while retaining its perpendicular orientation to its orbital plane.
