Mayan Jaguar Romaine Lettuce - Organic

(51 days) Although we’ve grown a lot of trendy splotched lettuces in the last decade, this cat’s mottled maroon spots on dark green ruffled leaves win the blue ribbon for most vibrant color definition. And it has great flavor, too, sweet juicy veins, blushed pink hearts and what breeder Frank Morton refers to as “that bone crusher romaine crunch!” It gets off to such a quick start, yet doesn’t grow very large or thrive in intense heat, making Jaguar a great candidate for early salad or mesclun. Fierce colors, snarly crunch, but really a pussycat at heart. OSSI. Seed purchased directly from the independent breeder.

Additional Information

Lettuce

Lactuca sativa

All lettuce is open-pollinated.
1 gram packet sows 25 ft; 2 grams, 50 ft; 1 oz, 500–700 ft. Varieties average 875 seeds/1g pkt, or 1,750 seeds/2g packet.

Culture: May be started indoors in March and at regular intervals thereafter, or sowed outdoors as soon as ground can be worked. Many varieties won’t germinate in soil temperatures above 75° and most shut down above 80°. Where available, we present data here from a California germination experiment at 84°.

Hardy. All save icebergs tolerate heavy frost. Grow best in cool weather with ample moisture, many kinds suffer bottom rot and tipburn in heat; select summer varieties carefully. Use shade cloth to keep summer lettuce tender and sweet longer. Sesquiterpene lactones produced in the latex render lettuce bitter when it bolts.

Sow every 2 weeks for continuous supply. Lettuce will not head unless thinned frequently and ruthlessly to final distance of 1'. Heavy nitrogen feeders.

Minimum germination soil temperature 35°, optimal range 40–80°.

Days to maturity are from direct seeding.
