Acer palmatum dissectum 'Tamukeyama'Japanese maple
A historic Japanese cultivar, documented since the early 18th century, ‘Tamukeyama’ combines a strong cascading structure with finely cut foliage of intense purple. The good persistence of its pigmentation through the summer makes it especially valuable among the red-leaved weeping Japanese maples.
- Old Japanese cultivar known since around 1710
- Strongly weeping branches that form a broad, dense, domed crown
- Purple foliage that holds through the summer, culminating in an intense scarlet red
About this cultivar
‘Tamukeyama’ belongs to the Dissectum group and grows as a shrub or small tree with a broad, dense, weeping crown. It generally reaches 1.5 to 2.5 metres in height and 2.5 to 4 metres in spread, although old specimens may exceed these dimensions. The horizontal spread of the crown is an essential part of its identity.Read moreShow less
‘Tamukeyama’ belongs to the Dissectum group and grows as a shrub or small tree with a broad, dense, weeping crown. It generally reaches 1.5 to 2.5 metres in height and 2.5 to 4 metres in spread, although old specimens may exceed these dimensions. The horizontal spread of the crown is an essential part of its identity.
The branches grow outwards at first and then descend in successive layers, creating a domed shape. When grafted on a tall stem, the growth forms a well-defined cascade; as a low form, it produces a broad, undulating mass that seems to follow the ground.
The leaves are made up of seven to nine narrow lobes, divided again into very fine segments. They emerge crimson red, turn reddish purple during the summer and end the season in orange and scarlet tones. The reddish petioles and young shoots reinforce the colour of the crown, while small purple flowers may be followed by samaras.
It holds its pigmentation well in hot summers when it has regular moisture in the soil. In Portugal it should be planted in morning sun or partial shade, protected from dry wind and the most intense afternoon heat. A rich, moist, well-drained soil, supplemented by an organic mulch, helps to keep the roots cool and the foliage intact.
It is suited to courtyards, Japanese gardens, banks, walls, water margins and raised beds. A mature specimen from Diaplant immediately brings an extensive, layered cascade, making it possible to select in advance the graft height, the crown spread and the distance needed for the branches to develop without interference.
