Mature Amelanchier alnifolia Obelisk– Alder-Leaved Serviceberry Tree

Amelanchier Obelisk Tree

Buy a deciduous Amelanchier Obelisk tree if you want a narrow, upright tree for a smaller UK garden. Amelanchier alnifolia ‘Obelisk’ offers a dense branch structure, interesting flowers, berries and autumn colour. ^{[1] [2] [4]}

This is one of the best columnar Amelanchiers for tighter spaces (small gardens, not tiny parking spots). Use it as a small garden tree, a narrow feature tree, a front garden tree, or a light screening plant where a broad crown would take up too much room. Mature size is usually around 4–5m high by 1–2m wide, with some suppliers giving up to around 6m in good conditions. ^{[3] [4] [5]}

In April, Amelanchier Obelisk produces an intense show of single white, star-shaped flowers with green centres. The new leaves emerge bronze, mature to green through summer, then turn orange-yellow in autumn. ^{[1] [2]} After flowering, the tree produces small dark reddish-purple to black fruits. They are edible when fully ripe, with a sweet, blueberry-like flavour. They can be eaten fresh or used in jams, jellies and pies, although birds often take them quickly. ^{[1] [2] [6]}

Amelanchier Obelisk is fully hardy for UK gardens. RHS lists it as H7, meaning hardy below -20°C. It will grow in full sun or partial shade, with the best autumn colour usually coming from a sunnier position. ^[2]

Planting an Amelanchier Obelisk Tree

Amelanchier Obelisk is wet tolerant i.e. damp or retentive soil, not standing water, and prefers acid to neutral, lime-free soil. ^{[1] [2]}

Plant Amelanchier Obelisk in full sun or partial shade, in moist but well-drained soil.

Water well after planting and keep the root area moist while the tree establishes, especially during dry weather in the first growing season. If grown in a container, use a large pot and keep watering under control, as container-grown trees dry out faster than trees planted in open ground. ^[1]

Pruning should normally be light. The natural fastigiate shape is one of the main reasons to buy this tree, so let it keep its upright framework. Remove dead, damaged, crossing or badly placed shoots, and lightly shape after flowering if needed. Avoid routine hard pruning, as this can spoil the natural columnar outline. ^{[1] [2] [7]}

RHS lists Amelanchier alnifolia ‘Obelisk’ as generally pest-free, although it may be susceptible to fireblight and honey fungus. Good planting, sensible watering and avoiding permanently wet, stagnant ground will give the tree the best start. ^[2]

Other Interesting Information About Amelanchier Obelisk

Amelanchier alnifolia ‘Obelisk’ is also seen under the name Standing Ovation, especially in North American plant information. This matters because some useful references to the same plant may appear under Standing Ovation serviceberry rather than under Amelanchier Obelisk. ^{[5] [6]}

The name ‘Obelisk’ is well chosen. Ebben describes it as a narrow upright cultivar selected from seedlings and marketed by Arboretum Kalmthout in Belgium in 1994. The upright shape is the key difference from many other Amelanchiers, making it a better fit for gardens where width is limited. ^[5]

See What Our Customers Are Saying About Our Amelanchier Obelisk

Alan, As the stern overseer of the garden I supervised the planting of our recent purchase by the resident husband. He did a sterling job and has tended it assiduously since planting. I inspected it earlier today and it is thriving, with several new leaf buds forming. As he has done so well he has now been elevated to Garden Dogsbody status. He's thrilled with the promotion. For the record, we also bought several Snowberries from you a couple of years ago and all are doing well with fat white berries weighing down the branches. Many thanks for the quality of the goods and we will no doubt be in touch when another shrub or tree takes my fancy. Janet 0917
