(Taxodium distichum (L.) Rich.)
-> Genus: Taxodium -> Family: Cupressaceae -> Group: Gymnosperms

Habitus

  • a tree growing in the homeland (southeastern USA) to a height of 30 - 35 (60)m
  • the crown is narrowly conical, deeply branched
  • the branches are arranged in a spiral
  • the bork is reddish-brown, cracked into relatively narrow longitudinal strips
  • the trunk is conspicuous in the lower part expanded - thickened (cylindrical) with significant root growth
  • on waterlogged sites it creates respiratory roots that grow upright from the ground

Shoots

  • produces two types of shoots:
  1. macroblasts - long shoots, they are permanent
  2. brachyblasts - shortened shoots, they are 50 - 100 x 1 mm in size, green, fall in autumn together with the needles that grow on them

Leaves (assimilation organs)

  • the assimilation organs are needle-shaped
  • the needles are 10 - 16 x 1 mm large, linear, pointed, narrowed at the base, light green, soft
  • turn brown in autumn and fall off (on brachyblasts together with brachyblasts)
  • on long permanent shoots (macroblasts) they are arranged in a helix
  • on shortened shoots (brachyblasts) they are arranged in two rows in one plane

Flowers

  • monoecious tree, flowers of different sexes, cone-shaped
  • ♂ cones are 1 - 2 mm large, ovoid, arranged in 7 - 10 cm long hanging broom-like inflorescences, grow on last year's shoots
  • ♀ cones are 3 - 5 mm large, spherical, grow individually at the end of last year's shoots

Fruits – seeds

  • the fruit is a spherical cone, 2 - 3 x 1.5 - 3 cm large
  • label is diamond-shaped, navel with blackthorn
  • cone ripens in the fall, it is decaying

Extension

  • originally the southeastern USA, on the banks of rivers, swamps of Florida
  • states around the Gulf of Mexico, the Mississippi River basin
  • on the territory of Slovakia it is found only as a cultivated species in parks and gardens
  • it was introduced to Europe in 1640

Ecology

  • a light-loving tree growing on the banks of rivers on deep loamy, sandy soils
  • it requires sufficiently deep soils with a high level of flowing groundwater (similar to the trees in floodplain forests in Slovakia - white willow (Salix alba), white poplar, Populus alba), ...
  • when young it is sensitive to low temperatures, later it resists frost

Significance

  • when adult, it is a majestic decorative tree with its habit
  • interesting with the formation of breathing roots
  • suitable for parks and gardens with water bodies
