Cracoviensis Looseleaf Lettuce - Organic


Cracoviensis Looseleaf Lettuce - Organic

(47 days) CR’s absolute favorite of all the lettuces Seed Savers curator M. Schultz shared, unlike any other in size, shape or colors. Cracoviensis is where the red meets the green, making a dazzling twisting rosette with heavy purple accenting, especially towards the center. Recommended for spring and fall culture, the plants grow fast and very large (14–16") in cool temps. Called “Bolt-o-viensis” by Scott Paquin, it sends up seed stalks with just a touch of heat. No matter: the leaves’ tender buttery flavor does not give way to bitterness even after bolting! Those thick fleshy bolted stems are prized in China where they are peeled and eaten like asparagus. Listed as a distinct type, Asparagus Lettuce, in The Vegetable Garden by Vilmorin-Andrieux (1885). Customers in New Jersey and Mass. have reported success overwintering it. 1996 Fedco introduction.

Additional Information


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.
