Super-easy to grow, even in 100+ degrees.

This plant is extremely invasive in FLA and I think it should be banned here. I've had it for over five years. At first, it was nice, easy to manage. Now it is unruly and I cringe when I see them. It will grow through your grass, all other plants and root systems of trees and is extremely difficult to kill.
Weed kill didn't work, vinegar didn't. I will try salt next.
You probably have to quaratine a large area where they are growing to really get rid of them. Where they have grown through the roots of my palms, I will forever be pulling at this awful plant to rid the sight of them.
The roots grow long and even an inch of this plant left in the ground will bring it back to life! Stay away from this plant if you love your garden.

I have not grown this plant. Ruellia squarrosa is also commonly known as creeping ruellia, trailing ruellia, creeping blue bell and blue shade. It is native to the central region of Mexico.

Will grow (and bloom) in shade but individual plant clumps don't spread out much locally and can get "leggy" with time; they prefer sun. Little plants tend to pop up all over since they spread by seed. I have transplanted many from sparse grass to sunny beds with great results. They grow where you plant them and frequently pop-up where you don't.

Very hardy in sunny, hot locations in North Texas/Southern Oklahoma. I have had these dwarfs for several years and the more I ignore them, the better they grow. Like lots of hot sun and seems to grow in any grade of soil. They multiply in the spring and throughout the rest of the summer. I pull up the babies (even soil-less) and give them to friends - I've populated half the world from 5 small plants 3 years ago. They grow well in pots also. Beautiful flowers with neat mounds don't get any easier than these!

Good Luck!

I filled in the data about this plant based on the label that I found in the nursery container. AS yet, I have no personal experience with it, but I soon will.

Hardy, compact returning year after year. Can stand the high Texas heat in summer yet hardy in freezing winters.

Easy maintenance. Great for a front flower border or even as a flowering ground cover along a path or sidewalk.
