Yes. Firs, spruces and pines all carry seeds on woody cone scales, so whichever of the three you carry home counts as a Christmas tree conifer by definition. The test has nothing to do with how green your tree stays through January. What settles the label is the way the plant makes seed. Cone-bearers do that inside a cone, and every species you find on a December lot belongs to the group. So you can stop wondering. Your tree qualifies.
My first winter after the seedlings went in, I ran a bare hand down a young spruce. I pulled back fast. The needles were four-sided and sharp enough to sting, each one set on its own small peg, and you can roll a single needle between finger and thumb like a short pin. The twig underneath felt rough where older needles had already come away. I have kept a glove in that coat pocket ever since, and nobody who has run a bare hand down a spruce in January forgets what it feels like.
A tree with no cones on it still counts, and that trips up plenty of shoppers. The group is defined by reproducing through seed cones, not by whether one young tree has yet produced any. Most trees on a lot get cut years before you would see a real cone crop, and plenty of the potted stock you find has never made a cone either. Lineage settles the question for you. A bare young fir sits with the cone-bearers the same way a kitten sits with the cats.
The names on the tags back this up. Fraser fir (Abies fraseri), Norway spruce and Colorado blue spruce all sit on the standard lists of coniferous species. Every Christmas tree conifer on those lists carries a needle pattern of its own, and needles are what you should read first. USGS points out that each red fir needle attaches on its own to the twig, while ponderosa pine carries needles in bunches of three. Firs and spruces go one at a time. Pines come in bundles, and you can call that difference from across the room.
Conifer and evergreen are two different claims about your tree. Most conifers do hold needles through winter, which is why you hear the words swapped, but larch drops every needle each autumn and stays a conifer the whole time. Holly keeps green leaves all year and is no conifer at all. Your tree earns the conifer name from cones. Your tree earns the evergreen name from the habit of hanging onto needles in the cold.
Living Christmas trees sell as a nursery category of their own, on the bench beside the miniature and dwarf conifers. Worth knowing if you want your tree in the yard come January rather than out at the curb. A potted tree stays a live plant the entire time you keep one in a warm room, so ask the nursery how long you should hold that tree indoors before you buy. You are shopping for a plant that has to go back outside.
On the lot, run a hand along a twig before you look at anything else. Flat, soft needles that bend mean a fir. Sharp, four-sided needles that roll between your fingers mean a spruce. Both belong to the same group, so the Christmas tree conifer question is settled before you touch a branch. The hand check tells you which of the two you are carrying home, and you can run one in two seconds while the seller is still cutting the netting.
