Trompenburg Japanese maple was found as a seedling plant in Dutch arboretum of the same name in Rotterdam. Its unique foliage, vigorous growth, and good health are something that makes me wonder why it is not more widespread and available in European nurseries and garden centres as opposed to other commercially successful red-leaved varieties which are prone to diseases.

Trompenburg variety has extraordinary leaves which are botanically classified as palmate (like all Japanese maples) but in this case they DO look like a palm (hand) with long fingers since the lobes are so deep and prominent, and the edges are curled downwards. They emerge rich red and quickly turn burgundy red with some brown and bronze shades towards mid and late summer. Autumn colour is bright carmine red and glowing wine red.

Trompenburg maple grows vigorously at high speed when young, making some 30-40 cm per year, slowing down with age. It forms a typical broadly vase-shaped multistem or small tree with umbrella-shaped dense crown. It can be trimmed to shapes or pruned to be kept smaller, best of which is done in mid or late winter during frost-free periods.

This maple needs full sun all day in order to produce its key colour. Grow it in semi-fertile, acidic to neutral, moist but well drained soil. Keep it mulched all year round and avoid growing grass above its roots. It will love a location with high air humidity, e.g. at a river bank or near a pond, but it is not a must. On the other hand it will definitely not be too happy in a small paved yard surrounded by dry air and hot concrete. Fully hardy to abt. -29°C (USDA zone 5).

Acer palmatum (
  • 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.
LARGE PLANTS over 150 cmspecimens, screening and hedging shrubs
