Tiger Eyes is trademark, cultivar is 'Bailtiger'. Same as cutleaf staghorn except leaves yellow. Introducer (Bailey nursery, see their web site) claims lower growing, but cutleaf staghorn sumac already more low and broad than typical.

Popped up in garden centers down here pretty quick, unless source(s) used in this area doesn't serve Lower Mainland would think you could find it with some telephoning.

I have two of the Tiger Eyes, both in the ground. The first one I planted year before last got munched on by the deer the following spring but it recovered nicely. This year I used some liquid fence just to make sure they didn't fine it as tasty as last year. They are beautiful and provide great color and texture! I hope you find one! Good luck.
