Short but very intense. Silky smoky mauve purple standards, velvety red black falls that give a shiny sateen effect under certain light conditions. Flared falls lightly ripple-ruffled, standards ruffled and slightly open. The finishing touch is indiscreetly bright tomato red beards. Terminal and three branches yield up to seven or eight buds.
Seedling #99-120C
