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 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'm open to any suggestions.
