I have two plants. Both bloomed when I first put them in the ground and not since then. That has been approximately 6-8 weeks. Good soil, well-drained, full sun, giving it minimal water only when dry. I did not upload a photo as it is just a healthy looking green. Thank you for having this \\\"ask section\\\" as I have been unable to find any information.
Likely, it will not resume proper blooming until next year. This year will be spent acclimating and healing over wounds from transplant.
Make sure that your fertilizer of choice does not contain too much nitrogen. This will halt blooming. Make sure that it is a well balanced fertilizer, or add extra phosphorus and potassium during times that it should be blooming. This will ensure that it has the proper nutrient ratios for blooming.

Ever year I get a hole being eaten into my flower stem to the point I usually only get one flower a year. This year every stem has been eaten. The rest of the plant seems fine.
Slugs and snails will eat them, but is this happening overnight? Go outside at night with a flashlight and see if the pesky critters are there. If deer have access to the garden and the stems are devoured overnight, it could be deer, but red hot poker is not usually on their menu. I would suspect the snails and slugs.
