annual herb
Shiso perilla
Shiso perilla is an annual herb noted for japanese culinary herb and red or green foliage. It grows in USDA zones 4a-10b, prefers part sun, full sun and loam and clay soils, and harvest timing is aromatic leaves in summer.
Fit and caveats
Shiso perilla is a tender warm-season herb for repeated leaf harvest. It should be planted after cold nights pass and pinched or harvested often before flowering reduces leaf quality.
Best fit
- Beds or containers in its listed growing range with enough light for strong flavor and enough drainage for the species.
- Kitchen gardens where frequent small harvests are practical.
- Gardeners who want fresh leaves more than bulk yield.
Use caution
- Most herbs lose quality if allowed to flower too early or dry down hard.
- Hot weather can make cilantro, dill, and some leafy herbs bolt quickly.
- Indoor windows are often too dim for strong long-term herb growth without supplemental light.
Regional notes
- In hot Southern ZIPs, many leafy herbs are fall, winter, or spring crops, while basil and lemongrass are summer crops.
- In northern ZIPs, tender herbs need frost-free timing and perennial herbs may still need winter protection or replacement.
- Containers are often the most practical way to separate herbs with different water needs.
Comparison note: Compared with vegetables grown for fruit or roots, Shiso perilla is more about repeated small harvests and flavor. Compare herbs by water need, winter hardiness, bolt tendency, and whether containment is needed.

Spacing, yield, and timing
How far apart should you plant Shiso perilla?
Plant Shiso perilla at 0.8-1.5 ft in-row x 1-2 ft rows. Adjust this starting point for trellises, hedges, rootstock, containers, pruning style, or local extension guidance.
How much does Shiso perilla produce?
Shiso perilla output is modeled as 8-18 weeks of harvest. Treat that as a planning range, because weather, soil, watering, pruning, pests, and local pressure can change the real result.
How long does Shiso perilla take to produce?
Shiso perilla usually reaches first useful harvest or display in 40-70 days under suitable conditions.
How do you grow Shiso perilla?
Grow Shiso perilla in USDA zones 4a-10b with partial, full light, loam, clay soil, and medium water. Use 0.8-1.5 ft in-row x 1-2 ft rows for layout planning. Match the plant to drainage, heat, chill, and pest pressure before scaling up.
Can Shiso perilla grow in a container?
Shiso perilla can start with a container of about 1+ gal (good). Larger containers usually buffer heat and moisture swings better than the minimum.

Right-size container with drainage
Containers / Before plantingUse a container large enough for mature roots, with open drainage holes to prevent root rot.
- View

Containers / Before plantingUse a lighter container medium instead of dense garden soil in pots and grow bags.

Timing / Before plantingCheck whether spring soil is actually warm enough for direct sowing, transplanting, and tender warm-season crops.

Site prep / Before plantingCheck pH and baseline nutrients before adding amendments, especially for fruiting crops, native beds, and acid-loving plants.
Planting strategy
- Planting depth: Set transplants at nursery depth or follow seed-packet depth for direct sowing.
- Container minimum: 1+ gal (good). Small herbs, leafy crops, and radishes work in 1+ gal pots or wider shallow planters.
- Start with one plant when testing fit in a new bed or container.
- Plant more than one when harvest volume or pollination is the main goal.
Risk factors
- Deer pressure: Not rated. No deer-resistance category is assigned yet; treat browsing risk as local and variable.
- Black walnut: Not rated. No black-walnut cue is assigned yet; verify placement if planting inside a walnut root zone.
- Match the site first: partial, full light, loam, clay soil, and medium water.
- Use 0.8-1.5 ft in-row x 1-2 ft rows as the first spacing model; adjust for hedges, trellises, containers, or local guidance.
- Plan around mature size: 1-3 ft H x 1-2 ft W.
- For harvest planning, treat "aromatic leaves in summer" and 8-18 weeks of harvest as planning ranges, not guarantees.
- Local drainage, pests, chill hours, wildlife pressure, and microclimates can change the result.

Sources and methodology
This guide combines hardiness range, light, soil, water, harvest timing, traits, supplier links, plant relationships, and quantitative planning metrics. Pairings are screened for practical garden fit.
Quantitative values use extension and botanical-reference ranges where available. For less-studied cultivars, similar crops fill gaps conservatively. Ranges are intentionally broad so the profile stays useful without pretending to be exact.
