Q.What Can I Do To Assist Cast Iron Plants Which Appear To Have Frozen ?
Several cast iron plants were planted in the shade of oak trees last October. We subsequently experienced a low temperature of -8 in an atypical winter storm here in North Central Texas. The once-green leaves are now totally tan, though some of the stems are still green. What should I do now: trim back to the green stems, replace the whole plants, leave the plants alone and see what happens?

They should be hardy to zone 7, which is to 0 degrees F, so doesn't bode well for -8 temps. However, since you see green, I would wait it out and see if they return from their roots. If you see new growth coming up, you can trim off the old growth.
