I Don’t Want Existing Plants on My Plant List in Vectorworks
If you are drawing a landscape project that has existing plants in it and you don’t want these to show up in the plant list, it’s easy to do.
Place all the plants that you want. If you create a plant list at this point, all the plants will be there. But let’s say that a few plants are existing and will be left, but you don’t want these on your plant list.

Select one of the existing plants.
On the Object Info Palette, find the option for
On Plant List
Click on this option to turn it off. Now this plant will not appear in the plant list.
If you change your mind, find the plant again, turn on the option for On Plant List
Then recalculate the worksheet and the plant will appear in the plant list.
