Of all the beautiful plants for sale at nurseries, florists, and grocery stores this month, the new Garland clematis is one of our favorites. Bred to thrive indoors, it comes with snowflake-shaped flowers in a range of delicious colors, from Cassis (royal purple) to Pistachio, pictured here. The vines are trained on circular frames in 6-inch containers and sold through December for about $20 each. To keep the plant tidy, tuck new growth beneath existing stems. Display in bright, indirect light, and water regularly.
