Since 2009, Sainsbury's has established the Longforgan, Perthshire grower as a regional supply base of branded herbs.
The new deal will bring a year-round supply of fresh herbs, with 80 per cent being field-grown locally during May to September.
Scotherbs managing director Ronnie Leggett said: "As part of the Sainsbury's Produce Development Group, we've seen the benefit of sharing best practice to address challenges and enhance the shopper herb offering."
The 20 products in the range are priced from 80p to £1.50.
A relative newcomer to Scotland, Sainsbury's now has 82 stores north of the border. It has over 550 lines specific to the Scottish market, and last year launched over 100 new regional branded lines.
