Starter plant of this Merremia umbellata or Hogvine. This relative of the Woodrose family is a perennial vine that is extremely hard to find in the US. Growing to 15 feet and showing off these sprays of cascading yellow flowers throughout the summer make this vine a keeper. Hardy in zones 8-11 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.
