Yellow trumpet not flowering

Hello Wildwoman
You need to go back 5 years now and try to recall where you got it from.
sometimes a cutting is taken from a Runner which is a side shoot that has grown at a rapid rate.
Sadly if this is the case it never flowers just grows at a fast rate repeating foilage after foilage but no buds.
Sorry,I hope this helps.
Best Wishes

Trumpet Creepers need to be pruned back vigorously in order to bloom. For 3 years i had no blooms but wanted to get some size to my plant (3 feet tall to reach the top of the fence) Then in the spring before the buds started swelling I attacked it. It grew like mad and had tons of blooms.
