My single Coconut Palms vary from 3.75" to 5" in height.   These require more than double the amount of time to produce, compared to my deciduous tree making.   But you'll appreciate the impact these will have on your model railroad, modules, diorama, or special scene.    They have a flexible trunk, so they can be posed to stand tall or bent.   Avoid touching the fronds.   These need delicate handling.   These are built similar to Luke Towan's.
