Costly Valentine

On the trail of the ephemeral
The astute and the perennial flower
Duped into a single day
And one incandescent hour
Which it knows will come again
Sooner or later in a year
On the trail of the ephemeral
Body where it goes green
And flakes off in a white storm
After much cogitation
It could be an eye or an iris
Fear is always of loss
On the trail of the ephemeral
Love is always the cost
