Rhubarb - Rheum rhabarbarum

Common Name:
Rhubarb

Description:
Rhubarb (Rheum rhabarbarum) is a hardy, perennial vegetable grown for its thick, tart-flavoured stalks, which are commonly used in desserts, jams, and sauces. The large, deep green, crinkled leaves form a striking contrast against the vibrant red or greenish stalks, making rhubarb both an ornamental and functional addition to the garden. It thrives in Melbourne’s climate, preferring well-drained, nutrient-rich soil with regular watering. Rhubarb grows best in full sun but can tolerate part shade. It is a cool-season crop, with peak harvest occurring in autumn and winter. The plant requires minimal maintenance, and once established, it will continue to produce for many years.
