Because Mars atmosphere is 96% carbon dioxide, any plants would blossom if they existed. All they are missing is a source of water.

While 78.1% of Earth’s atmosphere is nitrogen, Mars is only 1.9% nitrogen-based. Earth is rich in oxygen (20.9%). But we can only find trace amounts of oxygen on Mars. Other than trace gases, argon comprises 1.9% of Mars’ atmosphere.
