Extremely heat tolerant, this is a vining spinach that can grow up to 10 feet high with support. Flavor is the most neutral of all spinach vareities. Beloved for smoothies because its high anthocyanin makes a great purple color. A very tender, red-stemmed spinach with green leaves that grows fast. Not frost tolerant but perennial in greenhouses or with protection. 12 heirloom, chemical-free seeds per pack. Free shipping on orders over $34. Botanical name: Basella alba.
