Don't let last year's nevergreen tree cast a spindly, bare-branched shadow on this year's holiday festivities. Deck your halls, windows, oven racks, and pickup grills with today's Groupon to Garden Heights Nursery. You get $40 worth of evergreen wreaths, majestic holiday trees, pretty poinsettias, and holiday gifts for $20. Put your Groupon toward the quality Fraser Fir ($45-$200) to impress your guests or stock up on bountiful bunches of greens ($7) and place candles ($4-$12) dangerously near your effervescent pine. This Groupon expires on December 23, so either get a move on your holiday cheer or stock up on gardening supplies for the new year.Follow @Groupon_Says on Twitter.
