What color is the green unicorn?

Deer-tailed unicorn has copper-green skin and reddish-brown thorns, which are arranged in a T-shape, and are native to South Africa. It likes a dry and warm growing environment, and only by giving it a suitable environment during maintenance can it thrive. Usually put it in a well-lit place and get more sunshine, but pay attention to shade in summer. Its cold resistance is poor, so it should be moved indoors as soon as possible in winter, and the temperature should be controlled at about 15 degrees, not less than 5 degrees.
