Seeds from this Beaumontia Grandiflora or Heralds trumpet. This deciduous clinging vine can grow 15′ and produces these huge white flower blossoms from early summer right on through late fall in my zone 8B but is hardy in zones 7 to 10. Especially nice to grow over a trellis or privacy fence and will grow in full sun or part shade, producing more blossoms in full sun.
