Super Red Romaine Lettuce is a brilliant red. It grows in about 30 days for baby leaves and about 50 for full size heads. It holds up better than average in the heat and is also cold tolerant. You should put this into your garden, as well as succession planting every 2 weeks from Spring until Fall. Our Super Red Romaine Lettuce seeds are Heirloom and Non-GMO. Happy growing!!!
