JL Hudson has at least 2 one is the white one:
—Callicarpa americana var. lactea. (100) CALI-4A. Packet: $2.50
'WHITE BEAUTY BERRY'. Very attractive form with abundant white berries loved by birds. To 6 - 8 feet, with slightly cascading branches. Blooms mid-spring. Choice and rarely seen. Prechill 12 weeks.
I highly recommend Hudson, has many natives and unusual seeds, very reasonable prices and not dead or fake seeds like certain internet sites ae known for.
