Acer palmatum 'Sango-kaku' is the most well known Coral Bark Maple tree and has the RHS Award of Garden Merit. Acer palmatum 'Sango Kaku' produces bright coral pink young growth and yellow/orange, deeply lobed new foliage in the spring which turns to a lush green in summer and then striking soft yellow in autumn.
Once the explosive foliage display is over, the bare branches of 'Sango Kaku' make a stunning focal point in the winter. Triggered by a cold spell, the stems and bark turn a vibrant coral pink-red.
Offering year round interest, Acer palmatum 'Sango Kaku' makes the perfect feature tree for a sheltered position avoiding heavy, waterlogged soils. This red barked Maple will grow to approximately 4 x 2 metres in 20 years. For a very similar but smaller variety consider Acer palmatum Winter Flame or for a larger tree, Acer palmatum Beni Kawa.

Pot grown Coral Bark Maples can be planted at any time of the year. Choose a spot that avoids avoid heavy, waterlogged soils and remove all weeds and grass within a metre of it. Dig a square hole as deep as your root mass and approximately 2x as wide. To help your tree establish more effectively, we advise sprinkling root grow in the hole, especially if you have poor soil.
When planting Coral Bark Maples, use ericaceous compost when possible as this encourages vibrant foliage colour. Using 50% of the original soil and 50% compost, fill in the hole and firm around gently. Make sure not to bank the soil up around the collar of the tree as this can cause problems.
The tree planting guide has further information and videos.
If you’re planting Coral Bark Maples in spring or summer, water well and regularly for the first few months. If you’re planting in autumn, you may only need to water a little. Keep an eye on young trees and increase watering if there are extended periods of hot or dry weather. If possible, use rain water instead of tap water as this is more acidic and better for foliage colour. We stock a range of irrigation kits for more effective watering.
Once planted, keep the area free of competing weeds and grass for the first couple of growing seasons. If there is snow fall, gently brush the snow from the branches to ensure it does not weigh down the framework and cause damage.
Pruning should be carried out in the dormant season, from November to March. Japanese Maple trees bleed during other times of the year so pruning can weaken the branches. However, Japanese Maple trees very rarely need pruning. The natural shape is normally the most attractive and pruning should be carried out with a less is more approach. Only remove, crossing, damaged or diseased branches.

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. 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. Take care to buy a true multi-stem like all ours and not those that are 3 saplings in a pot to cheaply imitate them.
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
Premium Standard 10-12cm girth, approximately 3.0-3.5m in height
Heavy Standard 12-14cm girth, approximately 3.5-4.5m in height
Extra Heavy Standard 14-16cm girth approximately 4.0-6m in height
