My family’s red mulberry is the toughest one ive seen. Seems to have all the traits of a true morus rubra. Supposedly a true red mulberry should be hardy to Z3 or lower. I have only gotten truly ripe fruits a few times in my lifetime… the birds come from all over and know exactly when its ripe…
This one grows in the worst soil and underneath of driveways and is surrounded by paved roads. Its base rests on brick and block refuse and has been sprayed all around it with roundup for decades. It has survived alot of pollution as it lives in the heart of the ‘Chemical Valley’ of WV. Lots of acid rain and chemicals from the heavy industry of the 50s/60s and 70s. It has seen the roads nearby salted heavily every winter as well.
No matter what she still fruits and looks pristine and majestic.
