Rhubarb

Rhubarb serves as a bold architectural plant in garden design with its massive, dramatic leaves creating tropical effects in temperate climates. Its red stalks provide striking color contrast against green foliage. Excellent for filling difficult shady corners, stabilizing slopes with deep roots, and creating natural screens. The large leaves cast deep shade, suppressing weeds beneath while adding sculptural interest to borders and woodland edges.

Traditional Chinese medicine uses rhubarb root (da huang) as a powerful purgative and anti-inflammatory. The root contains anthraquinones, particularly emodin and rhein, used for treating constipation and digestive issues. Western herbalism employs small doses for liver support and detoxification. Caution required as leaves contain toxic oxalic acid. Root preparations historically treated fever, jaundice, and internal heat conditions in various traditional medicine systems.

Only rhubarb stalks are edible, requiring cooking to reduce tartness. Classic preparations include pies, crumbles, jams, and compotes, often paired with strawberries or ginger. The stalks provide vitamin K, calcium, and fiber. Forced rhubarb, grown in darkness, produces tender, sweet pink stalks prized by chefs. Never consume leaves due to dangerous oxalic acid levels. Stalks can be frozen raw for year-round use.

Rhubarb's extensive root system prevents soil erosion and improves soil structure through deep cultivation. Large leaves provide shelter for ground beetles and small amphibians. Flowers attract numerous pollinators including bees and hoverflies. The plant's oxalic acid content naturally deters most pests. Fallen leaves decompose slowly but eventually contribute organic matter. Established plants require minimal water, making them valuable in drought-resistant landscaping.

Perennial plant reaching 2-3 feet tall with enormous heart-shaped leaves up to 2 feet wide on thick, fleshy petioles. Stalks range from green to deep red depending on variety. Produces tall flower spikes with small greenish-white blooms in summer. Distinguished from similar plants by triangular leaf shape, prominent veining, and ruffled edges. Crown develops from thick rhizomes. Toxic leaves have smooth undersides unlike edible burdock.

Rhubarb has no timber applications as it's an herbaceous perennial without woody growth. However, dried rhubarb stalks have been experimentally used in composite materials and biodegradable plastics research. The fibrous stalks show potential for sustainable packaging materials. Large leaves historically served as temporary roofing in emergency shelters. Some artisans use dried stalks in decorative woven crafts, though this remains uncommon.

Rhubarb originated in Asia and traveled the Silk Road as medicine before becoming food. Victorian ladies used rhubarb juice as hair dye for golden highlights. The plant can live over 20 years, with some specimens documented at 50+ years. Forcing rhubarb in dark sheds creates an eerie popping sound as stalks rapidly grow. Alaska produces giant rhubarb due to long summer days, with leaves reaching 4 feet across.
