With an upright habit, Amelanchier canadensis 'Rainbow Pillar' is an excellent choice for small gardens. In spring, white star-shaped flowers are popular with pollinators. Mid-green oblong shaped leaves join the flowers.
The deciduous foliage turns stunning shades of yellow, orange and red in autumn and make it deserving of the name 'Rainbow Pillar' (it is also called 'Glenn Form'). Blue-black berries provide another feast for wildlife, in this case birds.
Growing to a height and spread of 5 x 2.5 metrs in 20 years, Amelanchier 'Rainbow Pillar' can be grown as either a small upright tree or slender shrub. It is a hardy tree that can cope in exposed sites and likes full sun or partial shade.
AKA Amelanchier canadensis 'Glenn Form', Serviceberry 'Rainbow Pillar'
Our pot grown Rainbow Pillar Juneberry trees can be planted at any time of the year. Start by removing weeds and grass within a metre of your desired planting hole. Dig a square hole as deep as your root mass and approximately 2x as wide. To help the tree establish more effectively, sprinkle root grow in the hole.
Remove the pot, gently loosen the roots and place into the planting hole. Mix 50% of the original soil with 50% compost and fill in the hole. Firm around gently, avoiding banking soil up around the collar of the tree.
We recommend using a stake and tie for single stem forms of Serviceberry (not bush or multi-stem). Insert the stake into the ground at an angle to avoid penetrating the rootmass, then secure the tree to it. Water around the base.
If you’re planting 'Rainbow Pillar' in spring or summer, water well for the first few months. Increase watering if there are extended periods of hot or dry weather. If planting in autumn, you may only need to water a little.
Once planted, keep the area free of competing weeds and grass for the first couple of growing seasons. If your area is prone to rabbits, use a rabbit guard.
Upright Serviceberry trees require minimal pruning and you can just remove crossing, diseased or untidy looking branches. They can handle hard pruning if desired but it will mean less flowering in the following spring, so we recommend leaving pruning until after flowering.
A good tip when pruning upright Juneberry trees is to remove any growth that is older than four years as this will improve the shape of your tree and encourage fresh bud and flower growth.

The product table at the bottom of the page gives the forms and sizes available for this variety. Please note, photos are a guideline as all plants are unique. *Pot sizes may vary. Below are definitions of terms:
Supplied Size: Height measured from the top of the pot.
Single Stem / Pruned and shaped: Classic shaped tree with a single stem that has had pruning to help create a beautiful, natural shape.
Top grafted: A height noted next to this form refers to the length of clear stem, which will not grow taller. Only the head of branches will develop. Top grafted trees do not require complicated pruning and are ideal for small spaces.
Feathered: A feathered tree has branches from the bottom of the trunk all the way up. These branches can be removed if a clear stem is required.
Multi Stem: A multi stem tree has two or more stems arising from or near ground level, growing from one root system.
Bush: A plant with many stems low down, rather than one clear stem.
Clump: Several plants in one pot that can give the appearance of a multi stemmed and very bushy tree.
Climber: A plant that is a natural climber and will be delivered usually running up a bamboo cane, ready to position in the garden.
Standard Tree: A more mature tree with an upright clear stem of approximately 1.8m-2.0m (measured from the soil to the lowest branches of the crown). Standards are available in different forms relating to their girth size (circumference of the stem measured 1m above soil level), not height:
Standard either 6-10cm or 8-10cm girth, approximately 2.5-3.0m in height
