Sambucus mexicana: Mexican Elder1

Edward F. Gilman and Dennis G. Watson2

Introduction

Mexican Elder is a semi-evergreen small tree, reaching up to 30 feet in height. Most open-grown specimens do not reach this height as they grow wider than tall. The light green, thick, leathery, pinnately compound leaves are often browsed by deer and livestock. The four to eight-inch-wide, flat cymes of yellow/white blooms appear mainly from April to June but in its native habitat may also occur at various times throughout the year after heavy rains. The small, blue/black fruits which follow the blooms are quite popular with birds and can be used to make wine or pies, and were reportedly even dried by Indians to be used at a later time. Fruits appear white because they are covered with a thick, waxy coating. A dye can be made from the stems and has been used to color baskets.

Use and Management

Trees are best located in the open where they can develop their low, wide-spreading, uniform crown. It might be planted near a patio, or as a small shade tree in a backyard garden but the dropping fruit can be messy on brick, concrete and other hard surfaces. Young trees often require training and pruning to speed formation of a uniform crown. Save the more upright branches and remove the drooping ones to create greater clearance beneath the canopy.

Mexican Elder should be grown in full sun on well-drained soil.

Propagation is by seed.

Pests and Diseases

No pests or diseases of major concern.
