Though rhubarb is technically a perennial vegetable, it’s generally considered a fruit for culinary purposes.
The leaves and roots of a rhubarb plant are potentially poisonous, but the red celery-like stalks have a rich and intensely tart flavor that complement sweet early summer fruits.
While green rhubarb varieties are generally more productive, red rhubarb is usually more tender.
Different varieties include Valentine, Crimson Cherry and Canada Red.
