Create List of Root-Hardy Shrubs
I'm in zone 5, IL. I am 100% positive Glorybower grows perfectly here, and as a bonus, it blooms on current "annual" wood:
'Peanut Butter Tree'/'Glorybower'
Clerodendron trichotomum (zone 7)
Lagerstromeia (indica x faurei) 'hardy hybrids' I have yet to plant any of these or research them, however, they were suggested to me by author, Guy Sternberg (link below)... if you'd like to read more about Guy S.
Thanks for your shared knowledge. It's most appreciated!!
p.s. I'm also growing Bee Bee tree which presumable should be hardy here, however, it came back from the roots and has only been in the ground for one year. (Evodia danielii/Tetradium danielii). ...I assumed this tree would be fully-hardy.
