Which flower relies on inherent rigidity rather than rapid water uptake to hold its shape when deprived of water?

Answer

Thistles (Eryngium)

Thistles, with their silvery-blue, spiky heads, rely more on their inherent rigidity to maintain shape, tolerating being out of water better than standard filler flowers.
