Viridis has become almost a generic term for green laceleaf Japanese maples. That's not a bad thing, but there may be better green dissectums. I have a Viridis that I planted nearly 10 years ago. It was originally in a sunny location but its leaves burned from the sun. So I moved it to a shadier spot, where it has thrived. Mine is about 4' tall and 6-7' wide now. Nice bright green leaves in spring/summer and gold in the fall.

Some other nice green dissectum varieties to look for include Waterfall, Lemon-Lime Lace, Filigree, Emerald Lace. Waterfall seems to be very popular in the nurseries lately and easy to find. However, if the nurseries in your area just stock Viridis, I wouldn't hesitate to buy one if it's a nice tree.

Called Viride Group overseas, because it is an aggregate of clones rather than a single clonal cultivar.
