Thujopsis dolabrata 'Variegata' (Variegated False Arborvitae, Variegated Hiba Arborvitae)


Michael's Opinion

A very interesting plant in that the foliage is always fresh looking and is speckled with large creamy blotches, it seems to have a little better form than the species and here I will contradict Michael Dirr and suggest this be planted more often not just in the collectors garden.

Description and Growing Information

General DescriptionIt is marked with creamy white spots which usually change back to the straight green form after a few years. It is more compact than other cultivars.
ID CharacteristicIt is dense but loosely pyramidal and very large. The leaves are linear with a silver underside. It has a sort of musty smell.
ShapeIt is a coarsely rounded evergreen.
LandscapeSpecimen and accent use, but not commonly used in a commercial settings. It is more of a collector plant although I think it should be used more often in shade gardens where its interesting form and colour will add dimension.
PropagationIt is best propagated from cuttings made in late November to early spring. They must be kept around 15-20°C for the initial rooting. All cultivars are rooted from cuttings made from current growth and taken with a heel November through May. If they are taken in or after January they will root more quickly.
PestsNone serious.
