Edward F. Gilman2

Introduction

A curious shrub with twisted stems and branches, walking stick slowly develops into a nice, rounded form (Fig.1). Branches grow upright when the plant is young, but eventually droop toward the ground. Flowers emerge and hang from bare stems before the foliage appears in the spring. Fruit is persistent and enjoyed by birds, rodents, and humans.

Most people plant walking stick in a prominent location in the landscape so its unusual habit can be displayed.

It can be used as the accent in any garden and is often placed near water, near a deck or patio so passers-by can enjoy it up close.
