The reason okra is so pretty is because it is related to the hibiscus.
If you have your TV turned up too loud and it (okra) hears frost in the forecast it will go ahead and die.
What I would recommend is to soak the seeds until they sprout/germinate.
Put seeds in proper containers and let it grow there protecting it from any freezes or frost.
When all signs of frost or freeze are gone plant it out.
You can plant the dwarf type or top a regular plant at around 2 feet tall, this will cause it to branch and put out more pods.
Cut the pods early so the plant will produce more.
