I'm looking for a perennial vine that will climb around a trellis that my husband built over the garage door to "girlify" his 36x40 foot garage! I would love something like trumpet vine or even wisteria, however, he doesn't want anything that will drop petals (or anything else) or more importantly, anything that could stain his cars.

Is there any type of vine that either flowers and doesn't shed too much or doesn't flower but still looks pretty (for zone 6)? I noticed the Hops Vine, but it looks like a shedder as well.

I'm open to any suggestions. Thanks in advance!
