Evergreens

Can you guess why these plants are called "Evergreens?" I'm sure it has to do with their color. Also, these trees keep their leaves all-year round.

According to Wikipedia,in botany, an evergreen plant is a plant that has leaves all year round. This contrasts with deciduous plants, which completely lose all their foliage for part of the year.

Leaf persistence in evergreen plants may vary from only a few months (with new leaves constantly being grown and old ones shed), up to a maximum of 45 years in Great Basin Bristlecone Pine Pinus longaeva [1]. However, very few species show leaf persistence of over 5 years.
