    Large 3" white trumpets adorn this vigorous perennial vine in summer and are born in clusters in the leaf axils. The White Sky Vine is vigorous enough to cover a 20' trellis by mid-summer and is considered a root hardy perennial into zone 8. The dark green, velvety foliage provides a nice foil for the pure white, yellow throated flowers.
