This is called Fasciation: I'm not sure what plant you have because of the unusual growth pattern -would need to see the normal plant growth. But here is some more info on it:

  • Fasciated stems are produced due to abnormal activity in the growing tip of the plant. Often an abnormal number of flowers are produced on affected stems. Normal branches may arise from fasciated stems
  • Symptoms of fasciation

    • Flattened shoots
    • Shoots that appear to be composed of several fused shoots
    • Flattened elongated or misshapen flower heads with numerous flowers

    Causes of fasciation

    Fasciation may be caused by:

    • Random genetic mutation or disruption
    • The bacterium Rhodococcus fascians
    • Viral infection
    • Damage to the plants by frost, animals (including insects), chemical or mechanical injury – even hoeing or forking around the plant have been implicated

    Control

    Affected parts of shrubs and trees can be pruned out if desired. Fasciation seldom recurs on herbaceous plants the following year.
