Small plants and tiny flowers add a lot of dept to a base. Unfortunately, most products you can buy don't really look realistic or are not available in the correct scale. I found a way to create my own plants in just a few minutes .
All you need is PVA glue, thin roots and some sort of leaves. I used linden leaves from plusmodels for my plants.
I drilled holes into a box and glued small parts of my roots onto it. The Colour pot shows the size of the roots. They should be rather small.
The linden leaves come in 4 to 5 different sizes and are slightly bent to one side. As they are made of paper, you can easily bend them into any form. The colour is rather realistic and doesn't need that much work during the finishing touches.
The largest leave is still very tiny. Make sure to turn away before sneezing. (not kidding, was no fun to recollect them)
....and bend the leave around your tool. The leave will keep this form, you don't have you use something to fix it.
