I'm on the fence of buying bobo hydrangea, I'm curious as to the size of how tall and wide they get. Does anybody have any pictures, when do they bloom? How do you prune them? Are they good for shade in morning sun in the afternoon and tips for planting them? Like fertilizer..how far apart to plant them?

Check out the hydrangea database with planting/care info and lots of photos. List of sub databases for plant groups appears on the right hand side of the page. I have found this quite helpful when deciding on plants to buy. The Hydrangeas Database

I would definitely buy one because I'm a hydrangea lover. these are smaller shrubs about 2' to 3' tall and as wide. my lace cap hydrangeas and paniculate hydrangeas are planted out front at my house and get full morning sun. I've got them growing in the back garden getting less sun, but it's afternoon sun. then the last bunch are in shade and they all bloom nicely. when planted i'd add some compost and water daily until they've settled in. as far as pruning, I do mine in the late spring and take off as much as I can to keep them shapely. this is for all my hydrangeas. I don't know if you'd have to prune this particular variety that much. it seems to keep itself on the small side. perfect for a large container.

Mop head hydrangeas are legitimately the best behaved shrub of all time, except for ( boring ) boxwood. I'm honestly not a huge fan of the flowers, maybe because I've seen them every year of my life.. all over the exact same plants....but they live forever, mature quick, tolerate dense shade, crappy soil, max about 4 feet tall, put up dense foliage so early in the spring they never need to be weeded- (and I live under a giant oak tree next to a woods full of invasive wild grape and kudzu.. .) they need a lot of water their first year... but once they're in, you're golden.. if they were evergreen they'd be the perfect landscape plant.

They will take full afternoon sun, if you're talking around 2-4pm till dark, but they can't take all day sun. You might get wilt when very hot and dry. Your first year, you will have to water them often, especially in very hot weather.. then almost never again.
Once, maybe twice a year they droop in August if we have 10 very hot days without rain, but quick hit with the hose and they bounce back right away. They are just so well behaved.. average 3-4ft sq at maturity they don't spread, they don't die, they don't misbehave They don't need anything. They look fur-fru, but they are hard as nails once established (after the first year). just cut the brown flower heads same time you do leaf clean up, otherwise they are maintenance free.

once they get established hydrangeas are pretty much maintenance free. I leave the flowers on until spring and then everyone gets cut back about 4 inches to the first set of healthy leaf buds. I also remove any dead stalks and clean up the plants if needed. They also do very well on the coast. the salt air doesn't seem to bother them. i have a variety of lace caps, mop heads and paniculates. love them all.
