General Notes

Tree with fine-textured foliage. Technically, the segmented branchlets are called cladodes. Fallen cladodes create a soft mulch layer beneath the tree. This plant is often mistaken for a conifer because of its cone-like fruit but is actually a flowering plant. Nice weeping habit, fast growing and tolerant of moderate frosts. The wood is used for furniture in Australia for its attractive grain.
