i'm not sure of the southern chances as it seems to be more of a cooler woodland plant (at least where i've come across it doing well). do you have any partly shaded areas with sandy/loamy soil?
also, the plant being very poisonous would be a hazard to children if they think the red berries are edible...
I tried it a few times and finally got it to grow AND come back this spring by planting under a big oak tree.
I built up a little area with good soil about 3' away from the trunk. I planted 10, eight came back this spring and most of them look like they've multiplied.
Here it grows like a weed, people call it invasive and warn about planting. I love it to are you tring to grow the pink color that can be tricky. White will need heavy shade in your part of country and lots of water.
I have a big patch on the N and NW corner of my house, shade to partial shade. They DO spread, so be wary about that. The shadier and wetter it is, the better they like it.
yes, that is how i've got the red astibile. in a low spot where it gets plenty of water. otherwise full sun most of the day. it's been there 10-15yrs by now. and in danger of being overgrown by trees.
