Hydrangea is a bit of an odd fellow. Blousy, chameleon-like, blue or pink, easy to grow yet wilts at the drop of a hat….its a bit of a mixed up kid.

Native Americans and settlers used it as a medicinal herb to remove 'gravel' from the bladder, to stimulate saliva, and as a diuretic, laxative or tonic.
The Japanese brew a sweet tea from the lacecap type, and some foolhardy types have even been known to smoke it even though hydrangeas are mildly toxic containing small amounts of cyanide. I'd give that a miss then….. And yet its used as a tonic in alternative medicine.
HHmmmm let's just say it's a great shrub for a sunny yet moist border and what gorgeous, perfectly round flowers.
