Even Cast Iron Plants prefer it indoors in Dallas as the cooler air these past 2 days in the mornings make them droop down as a result
Cast Iron Plant is pretty hardy. I had a few I separated at the roots and put in separate pots and placed on the front porch, but that was a few weeks ago, when lows were only in the upper 80s and highs the mid 90s. Now that it is nearing Autumn, a cold front has brought overnight temperatures down to the upper 50s, a good 30 degree drop on the low temperature of morning.
But as my Cast Iron plants set out on the front porch, I have notices as of these past 2 days, they are drooping. And that is a sign that they are suffering from shock. They generally fare well indoors and require only moderate sunlight through a window curtain or blinds. This time I decided to bring back in that one that I had cut 3 others from and had to give it time to recover from the shock of having part of it's root system cut away. The thing I like about this plant is, it is green year after year, and only every now and then a leaf will fade to yellow and I have to remove it but mostly the leaves of the Cast Iron plant are a deep green that makes the home a better place to enjoy.
