Perpetual Spinach (Silver Chard, 3 rockwool plugs)

Silver Chard 'Perpetual Spinach': Extremely heat tolerant spinach alternative. We left these unattended and unirrigated for almost 6 months in an allotment. The plants continued to thrive and leaves weren't even bitter. Cut-and-come-again. Harvest leaves from the bottom as needed, leaving the plant to continue growing.
