Sensation is a selection made by Warren Carnefix in 1980, Oregon, USA, and only recently has this tree been introduced to Europe where it is a sensation, too. This box elder is a deciduous tree with pinnate leaves that emerge coppery red and mature to rich green in summer. Still, top leaves of the crown or insolated shell of a shrub remain red all summer long like e.g. liquidambar acalycina until autumn when all leaves change to bright golden orange and red in autumn.

Sensation maple grows fast but a little slower than the species, making a good oval to rounded shape with age. In the nursery trade you can get shrub forms as well as half-standards, and obviously standard trees that look best, all of which show a dense habit and plentiful of colourful foliage to admire.

Ash-leaved maple can be pruned to achieve dense plants in smaller sizes or left to its own devices and you can be assured that it will develop a nice shape naturally once established. It can take almost any well-drained soil but prefers constant moisture and medium fertile soil. Grow it in full sun or only a light shade. Very hardy to approx. -45°C (USDA zone 2).

Liquidambar acalycina
  • STANDARD QUALITY - Plants of this group are 1st class quality with number of branches and overall density adequate to their size and age, considering they were container grown.
  • DE LUXE QUALITY - This label guarantees a luxurious quality of manually selected plants that, compared to their height and age, are exceptionally dense and beautiful.
  • EXTRA - These plants are usually mature and bigger specimens with exceptional overall appearance.
  • STANDARD (as described in the plant form) means a tree with a trunk of 190-210 cm and a crown at the top, unless specified differently. The commercial size for trees is their girth measured in the height of 1m from ground.
  • HOBBY - These plants are of the same quality as our standard-quality plants but younger and therefore cheaper.
  • SHRUB - a woody plant with branches growing bushy from the ground level.
  • HALF-STANDARD or MINI-STANDARD - a small tree with shorter trunk, its size is usually specified.
  • FEATHERED - These are trees with branches growing already from the base of the trunk and up along the stem.
  • GRASSES and PERENNIALS - Sizes given usually read the diameter of the pot or the clump, as specified.
