A giant golden pothos vine (Epipremnum Aureum) can grow in a large container filled only with water! These natives of French Polynesia are the giant versions of the common office/houseplant that many people call ivys. In warmer climates where they are not killed by freezing temperatures or just die down to the ground they can grow to the tops of trees reaching more than 60 feet and strangling them. In containers however, Giant Pothos are much more controlled. Give them a trellis support to climb for height like a few 6′ bamboo stakes shaped like a teepee and tied together at the top. You won’t be able to grow anything else in the same container but they are beautiful and majestic all by themselves. Giant Pothos will easily root and grow in water from cuttings. I found through a web search that you can purchase cuttings online for less than $4.
