70 days — 'Cimarron' is a very old Romaine/Cos type of lettuce. The leaves are a bright green color with a reddish-burgundy tinge, are crisp and quite flavorful. The medium sized heads stay firm and solid even in hot weather.
Does well in the North and is slow to bolt in the summer heat. Each packet contains one gram, which is approximately 500 to 600 seeds.
