Crisphead Lettuce

Joker Lettuce Organic

Joker Lettuce Organic


50-60 days. One of the most eccentric-looking lettuces we've grown, this harlequin of a crisphead produces dense, 6-8 inch heads that are crispy and tasty. The thick leaves have an emerald green background festooned with splashes and flecks of burgundy brimmed with toothy, purple/red edges. You'll be enjoying this lively 4-season lettuce in spring and into winter, as it's tolerant of both cold and hot temperatures and slow to bolt.

Days to maturity are calculated from date of direct seeding.

• Lettuce performs best in cool weather, 60-70°F, and grows in a wide range of soil types
• Plant as early as soil can be worked
• For extended harvest, plant every 2-3 weeks and choose heat tolerant varieties for summer
• A cold frame and cold-hardy varieties can stretch the spring and fall growing season into the winter months
• Apply 1 cup of TSC's Complete fertilizer per 10 row feet, and 1 inch of compost
• 1 gram of seed will sow 30 row feet
• Consistent, even watering is critical for best results

Direct Sowing
• Use row cover to improve germination and prevent soil crusting
• As soon as 2-3 true leaves have formed, thin loose-leaf types to 10-14 inches apart; icebergs, butterheads, and romaines to 12-16 inches apart

• Start indoors 4-6 weeks before anticipated transplant date

Insects & Diseases
Common pests: Aphids and slugs
Pest control: Strong spray of water for aphids or applications of Pyrethrin or Azatrol; baits, traps, or Cabbage Collars for slugs

Harvest & Storage
• While picking individual leaves helps extend the season somewhat, all eventually become bitter as they begin to bolt

What is pelleted seed?
Seed that has been coated with a clay-based material to form a larger, round shape. This makes planting by hand or mechanical seeder easier and allows for more controlled sowing of small seeds such as carrots or lettuce. All pelleted seed has a National Organic Program (NOP) approved coating.

Last year this was the only lettuce I ate, and next year it will be the only lettuce I grow - it is that good. It is meaty yet delicate. The taste is superior. I have never found this variety in the stores either. My favorite.
