Naming

Acer spicatum was described by Jean-Baptiste Pierre Antoine de Monet de Lamarck in 1786. The name is considered as validly published.

Acer spicatum is a species in the genus Acer which contains approximately 230 to 296 species and belongs to the family of the Aceraceae (Maple Family). The type species of the genus is Acer pseudoplatanus.

Acer spicatum - leaves

Growth

The shrubs reach heights of 7 to 8 metres, they have a erect habit and produce multiple stems. The main growing season is in spring and summer.

Wood and Bark

Leaves

Acer spicatum is deciduous. The dark-green, simple leaves are opposite. They are palmately lobed and petiolate with dentate margins and palmate venation. The foliage is dense in summer and porous in winter and turns an attractive red in autumn.

Flowers and Fruits

Acer spicatum produces panicles of erect, white five-stellate flowers from March to May.

From summer to autumn the shrubs produce an abundance of brown schizocarps that are persistent on the plant.

Root System

Distribution

Acer spicatum is native to eastern Canada, Saskatchewan, the Northeast of the US, the central Northeast of the US and the Southeast of the US.

Cultivation

The shrubs prefer a shady situation on moist soil. They prefer sandy-loamy or gritty-loamy soil with a pH between 4,8 and 7. The plants need a soil depth of at least 81 centimetres for good growth. They tolerate temperatures down to -45°C (USDA zone 2) and need a frost-free period of at least 14 weeks.

Tolerance of special soil conditions

  • none: soil salinity
  • low: anaerobic soil, drought
  • medium: calcareous soil

Uses

The ornamental value of Acer spicatum lies especially in the attractive autumn aspect. The recommended planting distance is 2 to 2,4 metres. The plants have only low potential for fuelwood production.

Maintenance and Propagation

  • Plants can be cut back down to the trunk (coppicing) as necessary.

Propagate by sowing. The seeds require vernalization.
