Is it too late to plant these as a border in Zone 6 area? If not, any
recommendations where to purchase them, and which one? Thanks

I have two penstemons, "Elfin Pink" and "Husker's Red." Both are blooming
now in my zone 6 garden. They are available at garden centers now, so there
is no reason to think you couldn't plant them now.
