Introduction

With attractive bark, good fall foliage color, and delicate pink blooms, Columnar Sargent Cherry is highly recommended for the home and urban landscape. Growing at a moderate rate into a 25 to 35-foot-high and 15 feet wide, upright to vase shaped tree, Sargent Cherry makes an ideal street tree casting moderate shade below. It is often grown with several multiple trunks or upright branches originating from the same position on the trunk ascending in a graceful fashion. This structure could be somewhat of a problem in ice-storms. Training to develop well-spaced branches along the trunk may help reduce this problem. The attractive cinnamon brown bark has a shiny, almost polished appearance with prominent lenticels arranged around the trunk. In late April or early May the one-inch-wide, pink to deep pink single blooms appear before the new red-tinged leaves unfold. The small, pea-sized fruits which follow are red, ripening to a dark purple in June and July. The fruits are considered inconspicuous due to their size and color but are easily found by birds who quickly devour them. The three to five-inch-long, shiny, dark green leaves take on various shades of orange, bronze, and red before dropping in late September, often well before other trees which are still green.

Use and Management

Sargent Cherry works well as a street tree (probably the best of the cherries for street planting) in areas which require a narrow crowned tree. It can be planted along the entry road to a subdivision or commercial landscape on 15 to 20-foot-centers or in the tree lawn space between the curb and sidewalk. It is also very effective as a specimen in the lawn or landscape bed.

Sargent Cherry should be grown in full sun on very well-drained, acid soil. Although it grows moderately fast and can reach up to 60 feet tall in the wild, Sargent Cherry is relatively short-lived with a 20-year lifespan, but provides reliable service during this period. It requires little maintenance once established and is quite tolerant of drought and clay soil.

Propagation is by grafting or budding.

Pests and Diseases

It is bothered by tent caterpillars, aphids, borers, and scales.
