Does it really live up to blooming all summer or is that just hype?

Almost. It first blooms on old wood and then blooms on new wood. There
is a gap where it is between old and new wood. Mine do well here in
Zone 6. I have heard some complaints from colder zones. Endless Summer
is a brand name and not a variety, since they have an entire series of
Endless Summer hydrangeas.
