I'm looking for a song by Donovan and all I know is that the name "juanita" is mentioned and a garden.

Answer 1

Is it There Is A Mountain? In the lyrics, it is spelled "Wanita", but that sounds the same as "Juanita"...so, I think this is it. Here are the lyrics:

The lock upon my garden gate's a snail, that's what it is.
The lock upon my garden gate's a snail, that's what it is.
First there is a mountain, then there is no mountain, then there is.
First there is a mountain, then there is no mountain, then there is.
The caterpillar sheds his skin to find a butterfly within.
Caterpillar sheds his skin to find a butterfly within.
First there is a mountain, then there is no mountain, then there is.
First there is a mountain, then there is no mountain.
Oh Wanita, oh Wanita, oh Wanita, I call your name.
Oh, the snow will be a blinding sight to see as it lies on yonder hillside.
The lock upon my garden gate's a snail, that's what it is.
The lock upon my garden gate's a snail, that's what it is.
Caterpillar sheds his skin to find a butterfly within.
Caterpillar sheds his skin to find a butterfly within.
Ah, my-my.
First there is a mountain, then there is no mountain, then there is.
First there is a mountain, then there is no mountain, then there is.
First there is a mountain, then there is no mountain, then there is.
First there is a mountain, then there is no mountain, then there is.
First there is a mountain
