I haven't had much experience with Hydrangea, but I bought a big beautiful 1
gallon size plant at Lowe's 2 weeks ago. I've got it planted and it's
thriving. My question is:

when I got it, the balls of blooms were standing straight up, but now they
are branching outward and some are lying on ground level. Is this the way
they are supposed to grow? I noticed at the nursery that all the others are
doing the same thing. I know they eventually turn into a nice sized bush, so
maybe this is a natural occurence?

Thanks
