Rheum: A Plant Genus Close to My Heart
My name is Ferb Vu, and I’ve always been fascinated by the natural world, particularly the plant kingdom. One genus that has always held a special place in my heart is Rheum, more commonly known as rhubarb. It’s a group of plants with a rich history, diverse uses, and a unique beauty all its own.
A Brief Overview of Rheum
Rheum is a genus of around 57 species of herbaceous perennial plants belonging to the family Polygonaceae. These plants are native to regions spanning from eastern Europe across Asia, with some species even reaching into the northern tropical zones of Asia. They are renowned for their large, somewhat triangular leaves that emerge from short, thick rhizomes. The plants also produce tall, upright stems that often bear clusters of small flowers.
What truly sets Rheum apart, however, are its edible stalks. Though technically a vegetable, rhubarb is often treated as a fruit in culinary applications. Its tart flavor makes it a popular choice for pies, jams, and other sweet treats.
