Fibrous Root System

A fibrous root system (sometimes also called adventitious root system) is the opposite of a taproot system. It is usually formed by thin, moderately branching roots growing from the stem. A fibrous root system is universal in monocotyledonous plants and ferns.

Most trees begin life with a taproot, but after one to a few years change to a wide-spreading fibrous root system with mainly horizontal surface roots and only a few vertical, deep anchoring roots. A typical mature tree 30-50 m tall has a root system that extends horizontally in all directions as far as the tree is tall or more, but well over 95% of the roots are in the top 50 cm depth of soil.

A few plants with fibrous root systems:

  • Coconut palm
  • Gabrielle
  • Pteridophyta
  • White clover (Trifolium repens)
  • Marigold

    Flower in the crannied wall,
    I pluck you out of the crannies,
    I hold you here, root and all, in my hand,
    Little flower—but if I could understand
    What you are, root and all, and all in all,
    I should know what God and man is.
    Alfred Tennyson (1809–1892)

    It is not easy to construct by mere scientific synthesis a foolproof system which will lead our children in a desired direction and avoid an undesirable one. Obviously, good can come only from a continuing interplay between that which we, as students, are gradually learning and that which we believe in, as people.
    Erik H. Erikson (20th century)
