Today's archetype is The Garden.
When it comes to exploring the archetypes of the garden, both time and place need to be considered. In classical and even through renaissance times, the garden was a place of joy and earthly delights. Stories that involved young or new love often took place in a garden, with its symbolism of love and fertility. It is a location used often by Shakespeare, but even the love stories of the Ancient Greeks often had people meeting (and often consummating their relationship) in a garden.
As Christianity spread, the meaning of the garden became a symbol of perfection or paradise. It is a source of both tranquility and idealism (Eden-like) and suffering, anguish and solitude (Gethsemane-like). Both of these are depicted in the idea of The Secret Garden (book or musical - I'm non-discriminatory). If you think about well known stories that have scenes in a garden, it is common to see the garden be a place of peace and comfort for one character while secluding another.
Finally, in contemporary times, a garden is a place for someone to tend. This often represents the way a person is digging into themselves, into their problems, not able to solve the world around them. It is often depicted as a sort of therapy, even if the character doesn't recognize it as such. Even in contemporary situations, the garden still has an inclination toward the philosophical (there's a really great post about how to incorporate gardening with a character here).
