Evergreen is a plant that stays all year round and is still green. There are many various types of juniper plants, including shrubs and trees. Evergreens have many coniferous species (such as fir, hemlock, blue spruce, red cedar), and mango.

Gymnosperms are conifers. They are cone-bearing seedlings with plant tissues, fruiting trees are all live evergreens.

4) Seasonally, deciduous trees drop their leaves, which include plants such as maple and elm.
