Description The name for this Japanese Cedar cultivar reflects the spiraling nature of the needles that seem to curl up upon themselves. In the trade it may be called Granny’s Ringlets.

  Morphology:
This is a garden conifer that grows into a dense pyramidal tree 20’ tall and 10’ wide. The branches are slightly pendulous. The needles are yellowish green and ½” in length. In the summer they are light green, but they can turn bronzy-brown during the winter. The bark is reddish in color and can peel.

  Adaptation:
In Japan, where this cultivar was found, it does best on deep, rich soil, plenty of moisture and protection from harsh winds. In northern latitudes it will need full sun.

  Pests:
None reported.
