Whorled

Def: Three or more leaves arising from a single node.


This is one of the more difficult leaf arrangements to identify. Many plants are listed as having a whorled appearance, but the leaves may actually alternate up the stem in a tight spiral. See Arrangement Along Stem under Arrangement: Opposite.

Note: In Central Illinois Catalpa bignonioides is our example of whorled arrangement.
