Here’s how I play it:

C > Am   Dm   G    C    G    F C

       C          G      C       C    >   Am      G
In the springtime of the year, I loved and lost my dear,
    C    >    Am            Dm            G       C         G       F C
For love grows wild when the weather it is mild, as you shall quickly hear.

      C            G          Am      F       G
Sweet thyme, sweet thyme, the parsley and the thyme,
    C   > Am         Dm    G    C       G       F C
The rosemary and the willow tree around my heart entwine.

C > Am   Dm   G    C    G    F C

    C       G    C             C   > Am       G
Now in comes sweet July when the nightingales do fly,
    C    >      Am       Dm    G          C         G         F C
And sweethearts play all in the hay and the pale moon fills the sky.

      C            G          Am      F       G
Sweet thyme, sweet thyme, the parsley and the thyme,
    C   > Am         Dm    G    C       G       F C
The rosemary and the willow tree around my heart entwine.

C > Am   Dm   G    C    G    F C

       C         G      C       C >    Am G
And the harvest's golden grain is gathered in again,
       C >    Am       Dm       G       C      G      F C
And the turning year will bring, my dear, an end to all my pain.

      C            G          Am      F       G
Sweet thyme, sweet thyme, the parsley and the thyme,
    C   > Am         Dm    G    C       G       F C
The rosemary and the willow tree around my heart entwine.

C > Am   Dm   G    C    G    F C

   C       G       C          C    > Am       G
In winter's cloak of gray, I'll find a brighter day,
    C    >   Am       Dm             G         C          G      F C
And I'll not wait when summer's at the gate, farewell false love, away.

      C            G          Am      F       G
Sweet thyme, sweet thyme, the parsley and the thyme,
    C   > Am         Dm    G    C       G       F C
The rosemary and the willow tree around my heart entwine.

      C            G          Am      F       G
Sweet thyme, sweet thyme, the parsley and the thyme,
    C   > Am         Dm    G    C       G       F C
The rosemary and the willow tree around my heart entwine.
