30 Chartreuse Whimsical Tree. With the Chartreuse Whimsical artificial tree, you will celebrate Christmas the way Dr. Seuss's reformed Grinch would. This bright green, glowing artificial Christmas tree is slim, and a little wiry, like you'd expect to see in the homes of Whoville. The PVC branches are prelit with green mini lights. Holidays are meant to be fun, so infuse your house with some lighthearted decor this year!
