If you have the winter blues, houseplants can always cheer you up - especially if they have colorful leaves and flowers! Some houseplants produce flowers under the right conditions - and you can find lots of colors, including shades of bright and cheerful yellow. So, which houseplants have yellow flowers? Houseplants with yellow flowers include Adenocalymma, Angel Trumpet, Belgian Mum, Brazilian Oxalis, Conophytum, Episcia, Faucaria, Gardenia, Nematanthus, and Trichocentrum.
