Not all OO gauge scenic materials do the same job. Here is a quick breakdown of what each one is actually for:
Twisted wire trees earn their place as feature trees that will be looked at closely. The cost and time per tree is harder to justify for areas further from the viewer, though some modellers use them throughout a scene where budget allows.
Heki trees sit in the middle ground. Ready-made, with more natural variation than standard plastic, they hold up well at OO gauge even when placed closer to the viewer. A strong choice for convincing woodland without the build time of twisted wire.
Plastic trees work best for background coverage where viewing distance does the work. Fast to place and economical across large areas, though the uniformity of moulded trees reads more naturally at a distance than up close.
Etched brass trees are for layouts where close inspection is the point. Exhibition standard, and priced accordingly.
Ground cover and scatter is not optional. Trees need to be rooted into something, and bare board underneath them is the thing that reads as wrong even when people cannot say why.
A scale chart is worth having before you order anything. At OO gauge, a 100mm tree represents around 25 feet in real life. Getting the height range right first means fewer decisions to unpick later.
