Tubular, star-shaped, red flowers and thin, ferny leaves makes Cypress vine a very ornamental climber.
It's in the same family as Morning Glory and grows just about as quickly, reaching 10 - 15 ft. in no time. It doesn't take as long as morning glories, to start blooming, but it will grow vine before it starts setting buds, so prepare to be patient.
Be sure to give them something to climb or sprawl over. They will grab hold of other plants, but if you are using a trellis, you will need to help them get started, twisting around it.
