Where do conifers grow?
Greece, Germany, China, India, Russia, Japan, Scandinavia, the British Isles, the Middle East, North America, Central America, South America, etc.
In other words, just about everywhere.
Conifers are simply cone-bearing trees. They include pines, cedars, junipers (which are excellent for Bonsai), cypress and yews.
You will need to be a lot more specific if you need a more precise answer. Sorry.
Conifers can grow in almost any habitat. Most of the time when people think of conifers they think of evergreen, needle-leaf, coniferous trees like pines, spruces, and hemlocks. These are very common at high latitudes in boreal forests, but some species do equally well and are not at all uncommon in southern ranges. Some grow well on the coasts like the Pinelands of coastal New Jersey. Some grow best in swamps like Atlantic white cedars…
