Put the roots of your love down with today's side deal. For $21, you'll get a side-by-side "couple of trees" planting (a $35 value) from Plant Trees 4 Life, an Aspen-based, not-for-profit organization, which is dedicated to environmental protection. Along with your pair of tree plantings, you'll get a Tree-Free certificate, which will be customized for your honoree.

Plant Trees 4 Life will be planting various native trees throughout the Monterey Peninsula. Your saplings—which can honor a loved one, commemorate a special event, or embody your affection for conical vegetation—will fill out the area’s embarrassing bald spots, pump out fresh oxygen, anchor the soil, slow down water run-off, and help maintain a lush ecosystem. While you won't be able to specify your trees' location, you can virtually visit planting sites on Plant 4 Life's website.

Providing much-appreciated shade to picnickers and housing baby squirrels, all Trees 4 Life's sustainable romance tokens will live on to benefit creatures both large and small. As any ardent arborist knows, a pair of love trees is a thoughtful gift for any eco-friendly fiancée, highly allergic honey, or natural niece. So, set two of them up on a blind date and watch them grow into well-rooted, sustainable soul mates.
