What smells of death

Hawthorn blossom smells of death
In the month of May
Could be my breath
Under a Hag horn some have said
Don’t ever place it near one’s bed
Apparently the trimethylamine
Really does smell quite obscene
A bit like when animals decompose
It truly does get up one’s nose

Joseph of Arimathea’s holy thorn
Was planted in Glastonbury
From his staff was spawn
A magickal sight for the bluest eyes
And all who saw it were ever wise
