Nice pics, Tex!
That wood betony sounds interesting.. I'll need to look it up!
Well, save the nice pot for something new and waylay a house-painter somewhere in town...
Tell him you are growing tobacco on your porch and need a couple empty 5's.
Painters are usually a friendly bunch... you may need to wash out a bit of latex, but that is ez enough.
Punch a bunch of holes around the side, near the bottom so water will drain out, and also may be brought in from a try below the bucket. Soak it for the first transplant, then water from the bottom thereafter.
Heck, it won't hurt much to water from the top!
You Will need a 5g bucket or the plant will die in the heat.
...next time around ask us for some seed and we'll see that you get some... far better than springing for a plant!
