Taxodium distichum 'Pendens' is a pyramidal, large-growing form of Bald cypress with horizontal branching and drooping or nodding tips. Over time it will form a wide pyramid, although young plants may be fairly narrow. Typical rate of growth in most areas is around 16 inches (40 cm) per year resulting in a 12 foot (4 m) tall and 6 foot (2 m) wide tree after 10 years in the landscape.
This is a very old cultivar that has been in the nursery trade since the 1850s. Elie-Abel Carrière (1818-1896) was likely the first to formally record and describe it. 'Pendens' has been confused with Taxodium distichum var. nutans as Carrière used this name but not in the sense of Robert Sweet or other authors for the true variety. [NewPlantPage.com].
