About
Shiso is the mint-adjacent annual with green or purple serrated leaves that sashimi plates and Korean pickles cannot live without. Self-sows like it pays rent in seeds — subtropical and tropical Americas gardeners either love the volunteers or learn to deadhead before the deed is done. Flavor is bold anise-cinnamon; not a shy herb. ☀️💧 Sun and Water: - Full sun to light shade; purple forms color best with sun. - Steady moisture; heat flags plants in dry pots fast. ✂️ Propagation: - Seed: surface sow after frost; cold stratification optional but improves some lots. - Transplant starts for head start against summer. Invasive alerts exist in some southeastern states — keep it in the kitchen garden, not the conservation easement.
Permaculture Functions
- Edible: Wraps, pickles, teas, rice seasonings.
- Pollinator: Flowering spikes attract bees and small beneficials if you allow bloom.
- Pest Management: Strong scent confuses some herbivores in interplantings.
- Ornamental: Purple cultivars are edible landscaping with zero apology.

Practitioner Notes
- Overfertilized fast growth dilutes flavor and invites sap feeders—lean soil often tastes more like itself.
- Morning photos for ID are useless if you only look at dusk—check midday nectar presentation too.
- Notebook one weird year—weather anomalies repeat; memory lies, scribbles do not.
- Soil smell and root color tell more than gadget overload—dig a small hole twice a season.
Companion Planting
- Tomato
- Pepper
- Basil
- Letting seed rain into natural areas where it is unwelcome
