In Kyuzo Murata's 1991 book, "Four Seasons of Bonsai" there is a photo of a chokeberry, Aronia, in his garden on page 110. The caption says; "Aronia arbutifolia, 30 years old, 33 inches tall. The red chokeberry is uncommon in Japanese bonsai, but it bears fruit reliably every year, and is hardy and easy to grow. Its trunks do not thicken at all, but its rhizomes will send up shoots everywhere, creating a natural group planting."
The photo is nice, a simple grove of a dozen or more trunks of various thickness, none looking thicker than an inch or so. Each trunk has a good crop of berries, looking quite attractive. The pot the planting is in looks like it is in a fairly shallow pot, like one would use for an elm or maple.
K. Murata was the caretaker of the Imperial Bonsai Collection of Japan for a decade or so, so if he says Aronia makes a nice planting, it is "official" as far as Japanese bonsai is concerned.
I know nothing else about Aronia as bonsai except for the information in that caption. Hope that helps.
