Ask Mr. Smarty Plants

Mr. Smarty Plants assumes that the vine is growing in California since you didn't indicate otherwise.  You can do a COMBINATION SEARCH in our Native Plant Database by selecting California from the Select State or Province slot, "Vine" from Habit (general appearance) and "red" and "orange" for Bloom Color.  This will give 3 results for native vines that grow in California.  In those 3 there are Lonicera ciliosa (Orange honeysuckle) with orange flowers and Lathyrus splendens (Pride of california) with orangish-red flowers.

It is entirely possible that the vine you describe is not a North American native plant.  Our focus and expertise here at the Lady Bird Johnson Wildflower Center are with plants native to North America so we aren't going to be very helpful in identifying non-native plants but we will suggest a couple that I found by Googling "California vine orange flowers":

Bignonia buccinatoria (trumpet vine), native to Central America.

Bomarea multiflora (Climbing alstroemeria), native to Columbia.

We are sorry but we no longer accept photos of plants for identification; however, please visit our Plant Identification page to find links to plant identification forums that will accept photos of plants for identification.
