Zac Efron treated girlfriend Vanessa Hudgens to a romantic 21st birthday present with a difference earlier this month - he planted three citrus trees on her Los Angeles estate.

The actress was shooting new movie Sucker Punch in Canada when she turned 21 on December 14, and when she returned home she discovered Efron had picked out a trio of fruit trees and hired a gardener to plant the lemon, orange and tangerine plants in her yard.

A source tells the National Enquirer, "Vanessa was incredibly touched by the gift."
