Fruit and berry tree types
Thank you for the question. I'm not sure what the plant in the first photo is. It might be choke cherry. If it is, the berries turn very dark purple, almost black in August and are edible when made into jelly. Please read through this publication on how to identify choke cherry. https://extension.unh.edu/resources/files/Resource001720_Rep2400.pdf
The next photo looks like a serviceberry of some variety. If it is, the fruits are edible. Read about it here: https://extension.umn.edu/trees-and-shrubs/serviceberry, and here: https://lancaster.unl.edu/hort/articles/2014/Serviceberry.shtml
The last photo is an apple tree, variety unknown. Determining variety is very difficult. You may want to wait until fruits are fully ripe and ask around your community for ideas.
Identifying plants with 100% certainty from photos is difficult so we do not recommend you eat any of the fruits until you have done your research and are satisfied that they are safe to eat.
Thank you for contacting Extension.
