Comments
Blooms May-November. Alamo Vine has large white flowers with dark burgundy centers, that bloom in the afternoon. The dark green foliage is intricately divided. The brown seed capsules resemble the flowers themselves. Fast-growing. Climbs by twining. Self-seeds easily. Can spread fast via rhizomes, so it is good for erosion control. Provides nectar to many species of butterflies.
