I'm glad you brought up this subject. I read all the posts this morning, and what
@TnBob said about, "They make the best jelly of anything I've had," was stuck in my brain...
I was driving into town today and saw something that looked a lot like Wild Black Cherries in the road, but... something wasn't right... The Wild Black Cherries mostly succumbed to the late frost we had here, and what few survived the frost ripened a month ago, whereas they're usually ripe about late June. And the stuff in the road was bigger.
I turned around, drove back past that spot, and lo and behold... Mullllllberries... and the tree was
loaded. I went on up to Clarksville, and on the way back, I pulled over to taste one... Had never tasted a mulberry. Wow! Sweet and delicious! I drove up to the house, talked to the lady that lived there, and she gave me permission to pick.
Drove home, switched to my truck, grabbed my 8' Tripod ladder, picking bucket, some ice water and a big pan to dump them into and drove right back. Picked 4 1/2 pounds before the thunder boomers were looming, but I'd just about picked it clean of the ripe ones I could reach, so I beat feet.
I did notice that this particular mulberry didn't seem to be sending out runners, so that just might be a characteristic of certain varieties... I know there are several types. Asian, North American, Black, Red, White and so on...
