Fading glory

I'm beginning to fade
But I'm not afraid
Of the dark
You all know the story
I've had my moment of glory
In the cool and the warm.
It's time to give way
To the glorious spray
Of forget-me-not blooms
And the aliums soon
Will need me to make room
So, toodle-oo, fare thee well
I've had my brief spell
In the sun.
