Whether you're shopping for a plant parent, a candle lover, or a home decor enthusiast, the Winter Spruce Glow & Grow Candle ($39) is such a clever gift that has multiple uses. They can burn the spruce-scented candle and get in the holiday mood. Once the candle burns down, they can reuse the ceramic vessel as a pot to grow their own white spruce. The gift comes with seeds, instructions, and everything else they need to make the plant thrive.
