Wisteria sinensis
honeydew
The Grape Vine produces grapes in clusters of fruit.
That really isn't enough information to answer your question. Please let us know what climate the flowering vine is growing in, what time of year you saw the flower, and, if possible, what shape and size was the flower. Was it trumpet-shaped? Was it a cluster of flowers? Wisteria is a vine with lavender flowers and a long, twisted seed pod. It grows in Mediterranian climates, but it is a perennial, not an annual.
Lavender will probably grow well where vine grows. The soil should be neutral to alcaline.

No
I believe you may be referring to Iochroma. The leaves (and even stems) of the plant are very rubbery and hold up extremely well in the wind. The flowers appear in clusters and are trumpet shaped so the hummingbirds love them. If you conduct a search you will see they actually come in various colors. Wonderful flowers for sunny locations!
