I had a few semps years ago. They didn't last long. Maybe heat, humidity, rain, freezes, harmonic convergence, who knows. I like them. I just seen to have troubles. About a year and a half ago I dove in again. I potted up a LOT of them. A couple of weeks later, we had the worst spring, then summer I can remember. Immediately after that, a massive heat wave and drought. I have no shade and sun can be brutal here as well. As to that, the squirrels wording dug them up for no apartment reason.

Fast forward, I am once again without Semps. So, yesterday I saw a heck of a deal and snatched up some more. I would love to plant these in beds outside but they would need to withstand sun, heat, humidity, and freezes. Additionally, I'd love to plant some in boxes on the porch but wonder if they could withstand being frozen solid in the winter... And potential high winter wind.

Thoughts?

Does anyone keep them outside in my region? Experiences?

I am in Texas so in the low 100's today.
When it gets this hot I use shade cloth . Cold is not a problem in your zone.

I use to live in the Evansville in area. I found summer requires shade cloth. I also tried to keep my somewhat dry because the rossettes would take forever to dry due to the high humidity. As for winter I would keep them covered if we were expecting a lot of rain. It's not the cold that does them in but the freeze and thaw cycles that area is prone too if they are wet. I remember I lost a ton one year when it went from 70 to 20 the next day. I also cover them if they are predicting ice.

Great information, Nathaniel.

Mine are all on the North side of the house, under the eaves, right next to the wall, in hopes they stay dry in winter and don't drown in summer.
I didn't cover them at all.
I also lost a lot, but I also just posted a few that survived.
I'm seriously thinking of bringing some inside tonight and for the next few days, since the heat index was 106° today.
Most are in smaller pots, so I could do that.
But I have to weigh the possibility of good against the possible length of time I'll have to have them inside and decide if I should, or if I should let them ride or die outside.
