I have okra that seems to be on steroids - are there different varieties?

I have been growing a variety of okra for the past several years that, if left alone, will have pods that reach 10-12" in length while green. I usually will pick the okra pods when they are 6" or less in length, because I find that when I try to cut/cook the very long pods, they are tough and stringy. So my recommendation is to pick your pods when they are short, in order to have more tender pods.

I usually only need 5 or 6 okra plants in my garden to get all the okra that I need; but in order to have only smaller pods to use, I usually will pick the pods from the garden every 2-3 days; most of the okra pods I will cut up in 1/4-1/2" slices and freeze them so that I can use them in soups, stews, and other dishes. Or I will keep a few whole pods from a day's picking in the refrigerator, and then roast them in the oven.

If I want to obtain seeds for the next year or so, I will let the pods grow to their maximum length and turn brown on the plant, then bring them inside and let them dry before recovering the seeds from the pods.

Short answer: yes, there are different varieties.

Every plant and animal that humans have raised has multiple varieties/breeds/cultivars/etc. We breed things for specific characteristics. And that's beyond what Mother Nature does herself.

Often there are hundreds of varieties but the number of them that are commercially marketed in mainstream USA can be counted on the fingers of one hand.

This Q&A forum is the wrong venue for a learned discussion on botanical diversity. Anyhow, here's a starter article on 13 varieties of okra:

in answer to your question, there are many okra varieties available to grow.

I suggest you take some photos of the plant and bring one of the pods to a local plant nursery and ask the staff. Most likely the local nurseries stock cultivars that work well for your local microclimate and soil. What is in your garden may be a decently marketed variety in your area but might be an oddity or unsuitable candidate for another part of the country.

You could post a photo of the plant here however there are relatively few gardeners frequenting this site. I would start at my local nursery...
