How long does it take for trumpet vines to establish themselves?

When can you plant the seeds for trumpet vines and will they amount to much here in the northeast?

Sorry....it sounds like a long time...Growing trumpet vines from seeds requires stratifying the seeds in moist sand at 39 degrees Fahrenheit and 30 percent humidity for 60 days. After planted, the seeds usually sprout within two weeks. Trumpet vines don't usually flower until they mature, which takes five to seven years.
You shouldn't plant them near your house. They will grow 50 feet or more.
