	I can't address winter hardiness of agapanthus in Zone 5, but can
certainly talk about Zone 7b.  We have been trialing agapanthus here since
the mid 1990's and are currently growing 59 different cultivars.  There is
a huge difference in not only survivability, but flowering.  We welcome
visitors to schedule appointments when they are in flower.

I'm 7b due to one or two days in winter when Siberia moves to "Jawja" for
some southern hospitality:)  Otherwise we have mild wet winters that are
also fairly short. So hardiness doesn't always translate well here.

another plant I would love to grow, and can't, since it is absolute lows,
not duration of winter, that gets them.  Then my 6 months of heat and
humidity coupled with ample (if unpredictable) rainfall in addition to red
clay hardpan add another variable to the mix.
