I love hydrangeas - especially blue ones. They scream 'cottage' to me. Unfortunately we have underground utilities running along our fence line in the back yard so I am limited in where I can plant things, but a couple of years ago I bought one little plant (blue - it was blooming when I bought it) and planted it in a pot. It has bloomed every year but after the first blue blooms died off it has only produced pink blooms - and I've put enough of that soil stuff into it to turn the whole yard blue.
The other day I counted 15 buds on my one little plant. I'm quite sure they will once again be pink but I'm okay with that as long as it blooms. Now I'm afraid to try moving it out of the pot!
We finally got approval to paint the house and we are on the painter's list but we don't have a start date yet - probably about 3 weeks.
