Hydrangeas.
« on: June 24, 2017, 20:26:06 PM »
The RHS spouts forth, on those, thus:

"The colors of some hydrangeas—especially mophead and lacecap—can change color based on the soil pH, which affects relative availability of aluminum ions. Acidic soils with a pH of less than 5.5 produce blue flowers; soils with a pH greater than 5.5 product pink flowers. White flowers are not affected by pH."

Sooooo... How come ours has blue flowers, pink flowers, white flowers and, even, green flowers, all at the same time?

Surely, the soil can't be both acidic AND alkaline, at the same time...?

It happens a lot, small pockets of chalk or acidic compost in the root run.

Really?

From what I can gather, it's been around for a bloody long time. According to neighbour who knows everything, it's been there for over forty years. So, I'm not worried about it, or anything. It' gives us all a great display, every year. Needs precious little, by way of care, too.

I can't say I've noticed any others that are multi-coloured, like that.

Ours is getting all autumnal, now. Still huge, though.

Hmmm... I wonder what The Yanks use, when their word for Autumn is "Fall"?

"Fallish"? "Fallal"?
