Lettuce, 'Jericho'

A great arrow in our romaine quiver, Jericho was bred to excel in the heat of summer with excellent resistance to tip burn. Don’t laugh. It gets hot here sometimes (way more often these days actually). No really! Remember that one time in 2009… Well anyway, hot season or cool, it’s one heck of a romaine at any time of the growing season. A beautiful and unusual luminescent chartreuse green color makes this savoy leafed, very large framed romaine a standout. Consistently drew compliments from our accounts when we grew romaine for wholesale markets and gaining traction among commercial growers.

Medium. Prefers well-drained, and evenly moist soil and is sensitive to low pH.


Uneven watering can result in tip burn, the browning of the leaf margins, which is the result of an inability of the plant to move calcium to the growing edge fast enough to meet its growth needs. Consistent, evenly moist soil or calcium amendments can be beneficial if this seems to be a problem.

Hot weather can cause premature bolting. Generally, when the plants begin to stretch upwards (to flower), the leaves become bitter and the eating quality poor.
