It does resemble Euphorbia lathyris, which is touted as having that benefit, though we cannot be sure of its ID while not in flower. You could ask if anyone using nearby plots has sown seeds of flowers for cutting or some other purpose. This Euphorbia is unsafe it consumed, though we have not encountered reports of it being dangerous otherwise (though sap from plants in this family has been known to irritate skin). Still, if it is inedible and growing in a collection of edible plants, it would be best to remove it lest someone accidentally harvest it (seeds have been mistakenly collected for pickling as capers). Used gloves to pull it up and dispose of it.

Thanks for your answer.  The plant is in bloom now.  The first picture is a close-up of the bloom and the second is a side view of a 60 inch plant  that is in bloom.   Is the plant Euphorbia lathyris?

thanks for your help.

It does seem like a match: https://plants.ces.ncsu.edu/plants/euphorbia-lathyris/.
We suggest pulling it out soon before seeds have time to ripen and be dispersed. You should use gloves and dispose of the pieces rather than composting them to avoid contact with the sap.
