Cheryl, So far so good on growing the Broms on the Plumeria. I also liked the look and have attached more.
I used a natural jute twine for attaching, as it will rot away on its own and will not cut into the Plumeria.
Position the Brom in a fork of your Plumeria and tie the Brom securely with the twine. After securing the Brom place a wet ball of sphagnum moss and secure with the twine. I finish off with the Spanish Moss to hide the twine.

Here is Neo 'Fireball' attached to the higher fork in the Plumeria.
Two great plants that I look forward to growing together.
