Fireworks Goldenrod

I have always been slightly puzzled by the name of this variety of Goldenrod
( Solidago rugosa 'Fireworks' )
But this year I saw it in a different light. On July 4th in California my family attended a fabulous firework display while we sat on the grass in the dark.

( I admit that a lot of my firework experience has been on rainy November nights in a British back garden with my Dad lighting the paper of rockets in bottles and running back to watch only to have the things fizzle out drowned by the downpour. We always had sparklers which could be enjoyed under a porch out of the rain.)
In sunny dry California the fireworks were fabulous ending in sparkling showers of shooting stars.
Just like this Goldenrod.

This website has some nice historical information about this variety
