Green Shiso (or Perilla) has a fragrant flavour that can be described as mixing notes of cinnamon, mint and basil.

It produces beautiful broad, dark green serrated heart-shaped leaves. It’s strong yet mysterious taste pairs well with fish and other seafood, rice, noodles and cucumbers. Baby leaves are excellent as a garnish and can also be added to salads.

Shiso has long been used in Japanese cooking and it is a popular herb in Asia. The flowers are edible too. It was cultivated in ancient China and is detailed in written records as early as 500 AD.

SOWING:

Best Time To Sow Seeds Sowing Method: Sow Direct or Transplant

Spring – Early Autumn

Sow Direct, or Transplant

Shiso seeds are best sown in spring through early autumn. Seeds should be sown in trays for transplanting, or can be sown directly in place after the last spring frosts approx. 10cm – 20cm apart, when soil temperatures are between 20°c – 25°c.

Soil Temperature To Germinate Seeds Time To Germinate Seeds

20°c – 25°c

7 – 21 days

Transplant seedlings, or thin directly sown seeds, once plants have some true leaves to a final spacing of approx. 20cm – 30cm apart.

Space Between Seedlings Approx Time Until Harvest Hardiness To Frosts

20cm – 30cm

65 – 100 days

Tender

TIPS:

Easy to grow and suitable for growing in pots and containers where garden space is limited.

Eat immediately upon picking for best flavour. Regularly harvest and enjoy the leaves for fresh use once your plants become established.

It grows to approx. 60cm tall. Please note that it is tender to frosts.

Botanical Name:

This is the formal scientific name for each plant, firstly identifying the genus and then the species to which it belongs.

The purpose of these Latin names is to have a single name that is accepted and used worldwide for a particular plant or plant group, and to help distinguish each plant uniquely from other plants.

Lifecycle:

This refers to the typical lifecycle of each plant.

Annual: Plants that complete their life cycle within 1 year (from germination to growing and producing seeds, then dying).

Biennial: Plants that complete their life cycle in 2 years (germinates and grows in the first year, then produces seeds and dies in the second year).

Perennial: Plants that have a life cycle of more than 2 years.

It is wise to consider the lifecycle of each plant before choosing its final growing position. For example, you may prefer to plant perennials away from annuals, so your perennials are not disturbed when your annuals are harvested at the end of their relatively short lifecycle.

Heritage:

This refers to the geographic region and approximate date of origin, as it is best known for each variety.

Please note that varieties listed as “pre 1900’s” are very old varieties that have often been grown for hundreds of years, and as such their specific dates of origin are hard to list accurately.

Best Sown:

This refers to when it is suggested the seeds are best sown, to encourage strong and vigorous growth in their ideal seasonal conditions.

Please note that while some varieties may be able to be sown outside the range suggested, they will generally perform best when sown in the approximate seasonal ranges provided.

Sowing Method:

This refers to the suggested method for sowing each variety. Using the appropriate sowing method will help to ensure you achieve best results.

Direct Sow: These are seeds that perform well when sown directly into your garden. These seeds normally produce fast growing and strong seedlings. Please note that young seedlings may still need some protection from harsh weather and pests.

Transplant: These are seeds that perform well when started in trays or containers and then transplanted to their final position once they’re a bit stronger. These seeds often produce slower growing and weaker seedlings that need some care and protection from weather and pests. Seedlings can typically be transplanted to their final position once they are large enough to handle (for example 5+cm tall with several true leaves).

Please note that for varieties where we list both methods you have the choice.

Soil Temp To Germinate:

This refers to the approximate soil temperature range for optimum germination of the seeds.

Please note that while some germination may occur outside these ranges, the seeds will typically germinate strongest when sown in the optimum soil temperature range provided.

Approx. Time To Germinate:

This refers to the approximate amount of time it takes for the seeds to germinate.

Please note that while some variation may occur, with ideal conditions this represents an average amount of time before germination. This relies in part on the seeds being sown in soil at an ideal temperature for germination, per the heading above.

Spacing For Seedlings:

This is the recommended spacing between plants in their final growing position.

Please note that spacing plants closer together than suggested will likely result in underperforming plants, due to crowding and over-competition for root space and available nutrients.

Approx. Time To Harvest:

This is the number of days until the plant typically reaches the purpose for which it is normally grown. For example, this is the time it takes for the plant to fruit or flower, or until the leaves are ready to be picked, etc.

Please note that while this refers to the beginning of harvesting time, the plants could keep growing for an extended period yet, particularly if kept well looked after.

Hardiness To Frosts:

This refers to how tolerant the plant is of frost and cold weather.

Tender: Plants that will be injured or killed by frost and cold weather. These plants will probably not survive winter.

Half-Hardy: Plants that will not tolerate severe frosts, but should otherwise survive winter.

Hardy: Plants that have the ability to survive frost and cold weather. These plants should survive winter.
