Shiso (Perilla) definitely demands to be treated like a warm weather annual plant. Set it out in pots or plant it outside when it's warm, in full sun. Or keep it as a houseplant or in the greenhouse. Shiso seems to have no particular pests apart from earwigs, and is not eaten by deer. But Shiso (Perilla) can't stand crowding, and it does need an adequate quantity of good soil, unlike many herbs.

Shiso leaves can be used whole or cut into strips, use the flower buds by collecting the seeds at the end of the season to sprinkle on salad and rice.
