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)

Crepe myrtle:

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.

Here is a link that might be useful: Wikipedia: Guy Sternberg

Dax, I've been growing Lagerstroemia indica here for a number of years and found it to be very root hardy and some seasons stem hardy. But I think I'm a tick or two warmer than you zone-wise. A good winter mulching is beneficial the first winter or two. We have some l.indica at the arboretum that are at least 15 years old.

I've heard of this growing up near Chicago and I know of several in this area - Musa basjoo. More of a tree than a shrub and does need some winter mulch to protect the roots.

Also if you can find a seed source of plants from colder than normal zones - eucalyptus. I had several species here for a number of years that did will - till I tried moving them - they didn't like that at all. Seems to me there are some folks out in Oregon that have good seed for colder climates. Might try Googling something like "root hardy to zone 5 eucalyptus". My seed source disappeared from the net so I can't help much.

Adina rubella, dies back to the ground in winter but comes back from its roots. It only grows about two feet high in NW Ohio.
