I am not in north Houston but I do have 3 plants that I try to give extra winter sun and air., Bell Pepper plant (new this year), Pink plumeria pudica, and the Tropical hibiscus. They sit closest to the front of the garage door where the winter sun points so the very least, they get light and air when the door is opened. During nice weather trends I can pull them outside. They are on furniture dollies. (Harbor Freight). The back of the garage door is insulated with mylar panels, but only right in front of those plants. I hope to insulate the entire door from the inside one day. The clivia sit up front too but not for sun. They like a bit of protected cold winter rest. The greenhouse plants stay put after theyve entered
