This plants grows vigorously in our zone in full shade. It is nice to have a ground cover that is so pretty and grows in full shade. It is a very vigorous grower, but it can be pulled up easily once or twice a year when it exceeds it bounds.

I love this plant. Mine is growing in very dry shade and it is thriving. It will tolerate our kids and very active dogs {Boxers} and never seems to have damage. I have it planted at the back of our property on the edge of the woods where the bunnies live and they do not seem to ever eat it. If they do it is not noticeable. Give it room it will spread quickly

One of the most invasive plants I've ever seen in my life...EVER, and I have EVERYTHING.

If something wants to live this badly, then perhaps I should let it...I think it's earned the right.

This is a great little fast growing vine which can be used as either a hanging houseplant, hanging basket planter outside, or a groundcover. It will recover from being very wilted with very little or no evidence of damage. In a pot, if it gets too big, just pull out your shears and cut it down to about an inch or two and in a few weeks it will be back thicker than ever. Cute little Snapdragon like yellow flowers.
