Last season I planted one in a pot and set it next to a fallen tree branch. As it grew i twined it around the branches and it spread out into a stunning display. Beautiful flowers covered the vines and it covered the entire branch. One of the most fun displays I've grown, and I cant wait to plant it this year!

I love the color of the flowers of this plant, although it hasn't been a vigorous grower. This is the first year I have had it. Recently I set it next to a bird mister, and the leaves are looking very spotted and blotchy. I take it, it does not like to have its leaves sprayed with water. I would love to know if there is anything else I can do to make it a look healthier.

Positively a stunning vine to grow, I had mine in a pot, it should have been a hanging basket! Went from pot on ground, up onto plant stand, again to a higher plant stand, AND still it wants to grow. next year it will be IN ground on a trellis of it's own, it is simply the most gorgeous color I have seen. Average watering and this vine will continue to bloom for months as it has done for me!
