Rhubarb Flower: What It Means and What to Do

Introduction

If you’ve noticed a tall stalk with a cluster of flowers growing from your rhubarb plant, don’t worry—you’re not alone. Rhubarb flowering, also known as bolting, is a natural process that can occur under certain conditions. While the flowers may look striking, they can affect the growth and productivity of your plant.

In this guide, we’ll explain why rhubarb flowers, what it means for your plant, and how to manage and prevent bolting to ensure a healthy and productive rhubarb patch.
