Anybody know a way to place an tree or other plants with script?

I work on an farming mod, I'm able to place mushrooms but not other plants.

The problem is to declaring property for plants.

mushrooms is flora and can be declared as
flora property mushroom1 auto
then link mushroom1 to the actual baseobject.

However I can not find how to do it for most plants who are of type tree and
tree property wheat1 auto
does not work as tree is not an property type.
Thought about formlists but they must also be declared by type.

any ideas here. it is possible as it's done in Heartfire.

I think theyre Activators. One of those

Thanks but they are not.
Found I could simply use an formlist with all relevant plants.
This also simply matching ingredients with plant to grow. looks as I could use this to spawn all sort of stuff. Plant an giant toe and get an giant

Lol that sounds pretty interesting

Thanks, it works nice, I can grow different plants and they grow back after harvesting them.

Last challenge is actually to select the ingredient to place, do you have any idea how to use a give interface filtered on the plants you can plant like in Heartfire.
Guess you have to use an npc, curently I'm trying with an container, however how do I check when the container is closed again.
