These seeds are forgiving. I didn�t water as religiously as usual, yet the plants grew tall with vibrant stems. Perfect for someone new to gardening.
I planted these seeds early spring, and the germination was excellent. The leaves grew large and tender, perfect for saut�s and salads. I�m really impressed with the flavor�it�s sweeter than store-bought chard.
I planted these to replace store-bought greens. The texture is amazing and holds up well when cooked. The stems are substantial but not tough, and the flavor is fresh and mild.
Out of 15 seeds, 13 sprouted quickly. The plants grew upright, with big ribbed leaves that look beautiful in my raised bed. Definitely ordering more next season.
From seed to harvest, the process was smooth. The flavor is slightly earthy but tender, making it great in soups and stir-fries. I love that it keeps producing for months.
