Originally from India, it’s probably the most striking blue flowered vine in the world, with a robust and twining habit producing long hanging clusters of 3? sky blue funnel shaped flowers from fall through spring. Can be trellised or arbored to create a spectacular sight! If they get a chill, they lose all foliage but roots stay intact. Fast growing sky vine reaches for the sky, decorated with ravishing summer flowers in blue with a hint of violet. You'll need plenty of room to fit one into your yard, but it can quickly fill in the blanks on an empty fence with just one or two plants. We grow ours organically with no chemicals, just compost.
