- Description
-
Taiwania cryptomerioides, or Taiwania, is an evergreen conifer in the cypress family and is related to the California Redwoods. It is native to Taiwan (the origin of its genus name) where it grows to 180 feet in the wild, but much shorter (30 to 40 feet) in cultivation.The juvenile needles resemble Cryptomeria japonica (Japanese red cedar). The tree features a conical to columnar crown, dark gray-brown bark that exfoliates in strips and dimorphic (having two forms) leaves. This tree is rarely found in domestic commercial establishments. Within its range, it is rather winter hardy and can be grown as an ornamental.
Best grown in moist, rich, acidic well-drained soil in full sun, although it does tolerate light shade. Do not allow the soil to dry out and plant in a location protected from winter winds.
