You could try Conny Schulte's Fredericus Rex online store: https://www.fredericus-rex.eu/index.php?language=en&& He's got some plants, albeit up to 54mm, but you might find something you can use, or leads to additional products.

Prost!

Your question made me do a search for myself, and I see a lot of products in HO scale for model railroads, but practically nothing in our usual scales or sizes. Conny's 54mm product covers that size, of course, but practically nothing for anything larger.

However, my search did return items for 3D-printed corn stalks, and that might be the avenue to follow. Here is one site that turned up in a number of hits:

The possible advantage with any 3D-printed item, of course, is the possibility that the item could be sized to meet your specification. You might want to take a look at this one, or see if other 3D printers can meet your need.

Hope that helps!

Prost!
