A plant sold as kirin palm may have a form or grafting arrangement that is not obvious from its trade name. Before removing an unfamiliar shoot, establish what plant you have and where the growth originates.
Photograph the whole specimen, the unusual growth and its point of attachment. Include any graft union or label that helps explain the structure.
A new shape is not a complete diagnosis
Growth unlike the crested portion may need management, but the correct approach depends on the actual plant and arrangement. Do not assume every upright piece is the same kind of reversion or that the same cut suits every specimen.
Seek reliable plant-specific advice before pruning an uncertain euphorbia. Appropriate handling also matters; this is not a job to copy from an unrelated palm-care video.
Keep the photographs and the confirmed identity with the plant's record. If a nursery supplied it, ask what was sold and whether it was grafted. That information helps you decide what to preserve, what may need removal and how to maintain the plant without guessing from the name on a decorative pot.
For Euphorbia lactea, NC Extension records both crested and non-crested forms and warns against contact with its poisonous milky sap. Wear protective gloves for plant-specific handling, and avoid cutting uncertain material before its structure and identity are understood.
