Ok @Fortheloveofbud. Found this...
Fasciation is described as abnormal fusion and flattening of plant organs, usually stems, resulting in ribbon-like, coiled and contorted tissue. The growing tip or apical meristem of the plant, which normally produces cylindrical tissue, instead becomes elongated perpendicularly to the direction of the growth or it splays out to the sides. Fasciation could cause plant parts to increase in weight and volume. There is often a concentration of leaf or flower buds in the area with fasciation. Consider it a plant mistake.
There are a number of possibilities as to why fasciation occurs that relate to hormonal, genetic, bacterial, fungal, viral and environmental causes. It could be any one of several reasons and none are within the range for the smart gardener to repair. However, those same smart gardeners will realize they just have to prune out the offending stem and the problem is solved in almost every case. As the plant continues to grow, there are no more plant mistakes.
Plant fasciation is one of the mysteries of the garden, but be a smart gardener and remove the odd growth. If nothing else, fasciation is fascinating.
