Some garden plants need a bit of a support to keep their foliage upright and tidy in the garden. A traditional English gardening technique is to use spring prunings from trees and shrubs as plant stakes, commonly called "pea sticks". The natural color of the twigs blends in nicely in the garden and soon becomes invisible as the plants grow up and around them. Hazel and birch are traditionally used for pea sticks, but most any woody species can be used. Pea sticks aren't just for supporting peas; they are also useful for pole beans, delphinium, campanula, or even top-heavy peonies and dahlias.
