Pollinator required to bear fruit

A cold-hardy, hybrid plum that thrives in cold climates!

The Alderman Plum tree is a Japanese x American hybrid plum developed and released by the University of Minnesota in 1985. This plum tree bears huge crops of juicy, cling-stone fruit – even after very cold winters!  

The plums are oval in shape, with burgundy-red skin that covers the golden juicy flesh. Sweeter than most other Japanese plums, Alderman plums are great for fresh eating and are prized for preserves and baking. The growth habit of this tree is round-headed and spreading. Beautiful white blossoms make their appearance mid-spring, with the fruit ripening in late August. Alderman is known to start producing in as little as one year!

Cross-pollination by a different variety is key to its growing and bearing success. Plant a different plum variety within 15 meters (50 feet) for best pollination.

    My Stark Alderman plum looks quite different to my other plum trees with it’s lighter colored leaves. But, it has grown very well since potting it for some months and then planting it in line with established Ozark and Santa Rosa plums. I’m looking forward to this tree bearing fruit early, as it has already grown a strong trunk with strong well spread branches. It is about six feet tall with a branch diameter of about four feet now – here in Alabama. I also noticed the destructive deer avoided it while munching tender leaves and twigs from my Santa Rosa and Ozark Premiere plums this fall. The Japanese beetles also avoided it somewhat for the leaves of the other plum trees. The beetles will no longer be a problem since I made heavy use of granules that destroy their larvae, and a new natural spray I’ve found that kills them in the mature stage almost immediately. The Alderman has grown substantially – on par with the Stark Ozark Premiere I planted in 2018 which is now around ten feet tall with a diameter of six feet or more of nicely spread branches. The new Ozark will likely bear fruit this coming season.

    Tree was sent as a whip, planted lasted fall in north central Arkansas, had a colder winter than average and it has put in roots and branched well as of June 9th 2022.
