Celtuce (Lactuca sativa asparagina) 1-1.5g/1000 seeds

Other names: celery lettuce, asparagus lettuce, stem lettuce, Wo Ju, Woo 
Chu, Wo Sun, Stemuretasu, Kaki-Jisha.

Celtuce is native to China. It is mostly grown in South China. It is a 
cool season crop. Seeds germinate poorly when
temperature is high. Usually, optimum germination temperature is 15-20℃. 
Except special summer cultivars, most celtuces
are sensitive to bolting in hot summer. Shortage of water and fertilizer 
as well as big day-night temperature difference
may contribute to premature bolting. Recommended planting density: 
20-30cm between plants in a row. For commercial
production, transplanting is recommended.

The stem is used for vegetable in China. however, the leaves can be used 
as lettuce for salads.
