Tsuga canadensis 'Jeddeloh' (Jeddeloh Hemlock)


Michael's Opinion

This is an interesting addition to you rock garden. The trademark central depression gives this dwarf conifer the nick name 'Bird’s Nest Hemlock'. It does not do well in hot or dry conditions, preferring partial shade and cool, moist, well-drained soil.
