Two fragments from old poems written about the same time, and clearly written at this time of year:
From The language of flowers:
[…] Shocking pink
petunias shout aloud,
while pompom marigolds,
in shades of summer, shine
like a myriad cartoon suns.
From In due season:
The hennaed heads of marigolds
rubberneck from roundabouts
and corporation window boxes shout
with yellow pansies.
