We've got some rough and ready bonsai and some others that are a bit more elegant. All by Walter Pall. 

I love everything about this tree. The lovely spring leaves, the pleasing shape of the crown, the profusion of rugged and distinctive trunks and and visible lower branches. And of course the powerful nebari. Here's Walter Pall's caption, "Japanese maple #30. About 65 cm high (26"). Pot by Walter Venne. Tree is originally from a cutting in a nursery in South Korea. It was imported to Germany in May, 2021."

Here's a beefy Oriental hornbeam by Walter. No leaves so you can see the profusion of small branches and twigs. This wild natural look is one of Walter's trademarks. 

Another Oriental hornbeam, but with leaves and a bit more pleasing to the eye. What a difference a few months make. 

Another rough and ready hornbeam. But this time a cascade. 

Aha, a little less rugged and a lot more elegant. It's Walter's Trident maple #11. About 50 cm high (20"). Pot by Walter Venne. The tree was imported from Japan in 2001 and was styled by Jurg Staheli of Switzerland until Sept 2019 and then by Walter. 

Another colorful Japanese maple. It's Walter's #17. height 40 cm (16"). Pot by Walter Venne. Tree originally imported from Korea.
