there are a few for sale as ornamentals
they do fruit, but they are hybrids and there is little flesh on the fruit.
i have 2 i got from a sale at Lowes for $2 each
its a good nitrogen fixing plant that keeps nice green leaves all winter.
the fruit has a nice taste, but very little flesh.
i have the latifolia i grew from seed
only 1 survived and it just lost its leaves in the freeze.
i had forgot it is a tropical relative.
autumn olive and russian olive can take temps below zero F.
