• 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
• Ring fasciation is where a ring of flowerheads are produced around a normal central flower, a phenomenon referred to as ‘hen and chicks’
• Plants commonly affected include delphiniums, euphorbias, forsythia, foxgloves, lilies, primulas and Veronicastrum
• Fasciation is unpredictable and is usually limited to a single stem. It seldom recurs the following year, although some plants, such as Forsythia and Veronicastrum virginicum ‘F²¹²õ³¦¾±²Ô²¹³Ù¾±´Ç²Ô’ do suffer repeat occurrences, perhaps indicating a genetic
  Genes are small sections of DNA that code for particular traits. During sexual reproduction, genes of both parents are mixed to create a genetically different offspring. Plants grown from seed may not be 'true to type' and look like their parents, but genetic variation can be beneficial, creating new, interesting characteristics and sometimes improving resilience to environmental conditions or disease. On the other hand, plants grown from cuttings are genetically identical to their parents. tendency to this problem
• Some fasciated plants are propagated to perpetuate their unusual forms. Ferns with fasciated tips often have names such as ‘monstrosa’ and ‘cristata’ and are highly collectable plants. The fasciated willow Salix udensis ‘Sekka’ is propagated from cuttings. Celosia argentea var. cristata carries its fasciation via seed, being a genetically

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

Fasciation may be caused by:

• The bacterium Rhodococcus fascians
• Viral infection
• Damage to the plants by frost, animals (including insects), chemical or mechanical injury – even hoeing
  Hoes are multi-purpose tools for weeding (especially between rows of veg), loosening the soil surface, making seed drills, earthing up plants, and more. There are various types with different shaped blades. Hoeing to remove weeds is best done on a warm, dry day, so you slice easily through weed stems just below the surface. or forking around the plant have been implicated

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