Rex lettuce must be one of the most popular butterhead lettuces in production today. It is a thick-leaved summer type but often used year round. Excellent quality, slow-bolting and very strong against tip burn, with a nice, clean and well-closed base, its leaves are not brittle and it is easy to cut. Resistant to Bremia BL 1-12, 17, 18, 22.
Unlike field varieties that are widely sold for use in greenhouse, these varieties are smaller framed allowing for higher plant populations with exceptional rates of growth that mean plants reach maturity much more quickly.
