Ruellia
brittoniana ~ Mexican Petunia
|
| Ruellia brittoniana is not
a plant for the faint of heart. The Mexican Petunia spreads
vigorously. Not so much as can't be contained, but not to be planted
and forgotten about either. Ruellia brittoniana can be kept within
bounds by planting in a container or in a restricted planter bed, or by
using drip irrigation so there is a small oasis in which it can
thrive. Ruellia brittoniana roots when the branches touch the
ground, spreads 6-12" per year by underground runners and has viable
seed. The Mexican Petunia has all of the tools to be a pest, though
I have not had too much trouble keeping it in check. Plants are
frost damaged in the 20's and killed to the ground in the teens. I
haven't seen weather yet to kill the roots.
