Marshmallow hydrangeas (flowers, grow, fertilizers, leaf)

[steiconi]

I got some cut flowers the other day labeled "Marshmallow hydrangeas". Each flower head is a mix of white and pink and yellow and green and blue.

Very pretty, I would love to grow these if I lived somewhere they could survive.

But when I Google Marshmallow hydrangeas, they are just one or two colors.

Is my bouquet painted or dyed somehow?

They can be dyed or they might have been fed at different times with fertilizers that have different PH levels or else they could be subjected to different kinds of light conditions when the flower heads were forming. My guess is both changes in PH and in light intensities. I have a dark ruby red hydrangea that changes from one solid colour to another to another depending on the light it gets. It goes from red to pink to blue-green to dark blue to purple and sometimes to yellowish-brown then back to red again. I think it looks like a freak sometimes. So I guess it might be possible to treat hydrangeas with supplements and light so they end up displaying multiple colours at the same time. I've never seen hydrangeas like that.

After asking, I noticed a splatter of pink on one leaf; I'm guessing at least one color is paint.

Thanks for the run down on hydrangeas. I knew about acidity, but not the other color factors.
