Hi Rhiannon!

I believe the version you are looking for is the one I sing. I got this from Janet & Tony Geen who had the copy of the original broadsheet.

Chorus) Won’t you buy my sweet lavender
Sweet blooming Lavender
Oh buy my pretty Lavender
16 bunches a penny.

1) Buy some for your lady sir
Sweet blooming lavender
Oh pin them to her bonnet sir
16 Bunches a penny

2) Picked them fresh this morning sir
Sweet blooming lavender
See the dew a glistening there
16 bunches a penny

3) Buy some for my sucour sir
Sweet blooming lavender
Bless you for your kindness sir
16 bunches a penny

Hope this is the version you're looking for.
Love
Pearl
