I planted the seeds at my back-fence trellis last spring, where the lawn meets the south-facing wall. By June the red flowers opened with the morning sun on them. Then it hit me that this vine grows in no forest, no field, and no roadside on Earth. Cardinal climber has no native range of its own, because someone built it on purpose from two other plants.
So the short answer to your question is no. Cardinal climber is not native to North America or to any other place you can name. The whole cardinal climber native range idea has a strange answer for you. A true range only belongs to plants that grow in the wild on their own, with no help from a gardener.
The cardinal climber hybrid origin goes back to a man named Logan Sloter. He began crossing two related vines in the United States in 1897. His goal was one plant with the best traits of both parents. The result was a brand new garden plant that had never grown in nature before his work. That is why you will never trip over it on a wild hike.
Both parent plants come from far to the south of you. They are native to Central and South America, where the warm air lets them climb and bloom for months on end. Sloter took those two tropical vines and bred them into the single hybrid you can buy today. The child plant carries the looks of both, but it owns no wild ground of its own.
Because it is a made plant, it leans on people to spread. You sow the seeds each year, and it shows up in beds and on fences around the world. Growers treat it as a pure ornamental plant for color, not as a wild species. You will find it climbing yards far beyond the home range of its parents, from cool northern gardens to warm patios.
This matters for how you plant it in your own yard. You do not need to worry about it taking over a meadow or a creek bank near you. In most regions your cardinal climber will die back with the first hard frost, so it cannot dig in and run wild. You start fresh from seed the next spring if you want it again, which keeps you in full control of where it grows.
The vine has slipped past garden fences in only a handful of warm spots. Records show it has escaped cultivation in just a few states. The short list is Texas, Florida, and Michigan. Outside those few places it stays put in the gardens where people choose to plant it.
That small spread does not give the plant a true wild home. A few stray seedlings near an old garden are not the same thing as a real native species. A native plant builds its own range over thousands of years, with bugs and birds and weather all tied to it. So the honest reply to is cardinal climber native to your region stays a clear no.
You can still want a vine that truly belongs to your area, and that is a smart goal. A native climber feeds local bees and birds in ways a hybrid often cannot. The good news is that you have a strong swap ready to plant in its place.
For a true native climber with the same morning-glory look, NC State lists Ipomoea pandurata as a solid choice. It climbs much the same way as cardinal climber, and it has real roots in North American soil.
I pulled my own seed packet to check, and the label backed all of this up. So enjoy the bright red blooms on your trellis for what they are. Cardinal climber is a man-made garden flower, not a piece of the wild, and that is a fine thing to grow on purpose.
