HORTICULTURE

Detailed explanation-1: -evergreen, any plant that retains its leaves through the year and into the following growing season. Many tropical species of broad-leaved flowering plants are evergreen, but in cold-temperate and Arctic areas the evergreens commonly are cone-bearing shrubs or trees (conifers), such as pines and firs.

Detailed explanation-2: -Trees known as evergreens keep their leaves, called needles, all year. You can determine an evergreen by its continuous showing of foliage during cold months while other trees lose leaves. Pine trees, spruce trees, palm trees, holly trees, and Murray Cypress trees all keep their leaves year-round.

Detailed explanation-3: -Evergreen trees keep their green leaves year-round. Many evergreens are coniferous trees, or conifers. Typical conifers include pines, firs, cypresses, and spruces.

Detailed explanation-4: -These trees first came from colder climates, so they are adapted to lower temperatures. The shape of their needles means that they can conserve more water and the needles also have a waxy coating to help with this. The needles also photosynthesise more slowly, but keep doing so all year round.
