I don't even know what stratifying is!
From Shiso (Perilla frutescens) | The Good-To-Know | Seeds A-Z | Seed catalog P - Samen & Saatgut
Perilla frutescens may well be considered a classical window sill culinary herb. Shiso needs light to germinate and should therefore only be lightly pressed into the soil. When they are started indoors, they need a short cold stratification to simulate the winter season. Sow outdoors either in late fall or early spring, before the last frost. Choose nutrient-rich and well-drained soil and keep sufficiently moist, but avoid waterlogging. Perilla thrives in the sun and in partial shade.
Just stick them in the freezer for a few days. Again, it can take a long time for them to germinate. The first time I grew some it was close to a month.
