Help with Japanese text for Pokémon Art.

Hi guys.
I'm doing some art and merch based on Pokémon.
I'm working on a Grookey based piece as you can see.
I'm doing posters and Shirts but before that, I'd like to add some Japanese Text.

I'd like it to say Grookey's Tree (SARUTONI'S TREE) in Japanese.

I used Google translator and it says it should be :

SARUTONI NO KI (サルトーニの木)

But I don't really trust Google translator.
So I come to you Reddit experts. What would be a good translation for that text.

Thanks a lot <3
