What type of trees can Ueki make?

Question

In the anime Law of Ueki, Ueki has the power to "turn trash into trees".

What kind of tree(s) does he turn trash into? Can he control what tree he creates?

Answer 1

As per the wiki

Although the power to turn trash into trees may seem weak, Ueki can be creative with it, making wood darts, wood clubs and wood vines. He is able to win most battle which may seem impossible, beating someone with 299 talents when he only had 11. He can even make trees strong enough to travel directly through cars.

Its seen that he can make any tree he wants, making a chestnut tree to counter Taira's fire attacks with the chestnuts flying out of the tree and shooting at the opponent(but really wanted to make them hot enough to eat).
