Biennial, 30-50 days after germination heirloom. Also known as Spinach Beet. If your summer spinach is always running to seed before you manage to get a worthwhile crop off it, then Spinach Perpetual is the variety for you because it virtually never runs to seed in its first season, therefore very good on dry ground. Spinach Perpetual is succulent, prolific and very hardy, suitable for autumn and winter crops too.
