Smoke Tree

Cotinus coggygria

Smoke Tree is a substantial deciduous shrub with an open, spreading outline, reaching about 15 feet tall and 12 feet wide. Its airy pinkish, smoke-like plumes create a soft summer veil, followed by vivid fall color. Use it where that changing silhouette can be seen against a simpler background rather than packed into a densely layered planting.

Placement and use

Give Smoke Tree a sunny position at the back or outer edge of a large bed, where its height can rise behind lower shrubs and perennials without narrowing the planting area. It works especially well as a single focal plant or repeated in a loose boundary planting, with open ground around its branching form. Keep it away from tight corners, narrow side yards, and the inside edge of paths so its broad canopy does not crowd circulation as it matures.[1][2]

Spacing and mature footprint

Plant Smoke Trees 10 feet apart, center to center, when arranging a row or repeated grouping. Each plant can eventually occupy about 12 feet of width, so allow the outer growth to overlap only where a continuous, informal screen is intended. For a specimen, reserve a full-width planting zone and leave enough adjoining open space to view the summer plumes and reach the base for pruning.

Three plants set 10 ft apart, center to center; shaded circles show the 12 ft mature spread.

Sun, water, and soil

Place this shrub in full sun and use it in a well-drained part of the garden. Its low water needs and tolerance for poor soil make it a useful choice for sunny beds that are not kept richly amended or consistently damp. Avoid making it the visual center of an irrigated border whose surrounding plants require frequent watering.

Seasonal notes

Late spring to early summer bloom begins the plant’s show, with the smoke-like plumes carrying its presence into summer. Fall color gives the same footprint a second strong season, so leave sightlines open from a patio, entry, or main path. Because it is deciduous, its winter framework can also be allowed to define the back of the bed.[1][2]

Planning caveats

Treat pruning as a design decision rather than routine shearing. Hard cutting in late winter or early spring can keep the plant more compact and produce vigorous leafy shoots, but it can reduce or sacrifice that year’s flowering display. If the airy plumes are central to the plan, allow room for its natural outline and limit pruning to selective shaping.[1][2]
