Thanks, Janet. That's what I thought. It's preposterous, isn't it? He says they're five feet across and a foot between leaf nodes, which would mean there'd be only 5 pairs of leaves on each of the arching canes. Obviously, the figure's closer to 50 pairs than 5.
At any rate, although this probably is a Symphoricarpos rather than a Breynia, the common name of S. mollis also makes me doubt the identification. No one would describe my shrub as a "Creeping Snowberry." It's as tall as it is wide, and it's absolutely unsuitable as a groundcover plant.
