Hibiscus before the rain!

How come I have about 30 beautiful blooms on my hibiscus but only one flower has this pink stripe? Perhaps it is weeping at the rain scheduled for the next few days/forever.
Went back to the sulpture walk again today and had a little spend. My sister will be the happy recipient of my little spend! I can hear her saying 'coo'!
The rain is now pouring down and everything in the garden is getting bashed. I will be weeping next - never mind my hibiscus!
