Acer palmatum ‘TROMPENBURG’

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).

Description:

This cultivar’s unique leaf shape, combined with the tree’s naturally beautiful structure and color make it an excellent choice for the garden as a focal point; a favorite for its incredible crimson fall color

Ornamental Features

Trompenburg Japanese Maple has attractive deep purple foliage which emerges red in spring. The deeply cut palmate leaves are highly ornamental and turn an outstanding crimson in the fall. It features subtle corymbs of red flowers rising above the foliage in mid spring before the leaves. It produces red samaras from early to mid fall. The rough gray bark and red branches add an interesting dimension to the landscape.

Landscape Attributes

Trompenburg Japanese Maple is a deciduous tree with an upright spreading habit of growth. It lends an extremely fine and delicate texture to the landscape composition which can make it a great accent feature on this basis alone.

This is a relatively low maintenance tree, and should only be pruned in summer after the leaves have fully developed, as it may ‘bleed’ sap if pruned in late winter or early spring. It has no significant negative characteristics.

Trompenburg Japanese Maple is recommended for the following landscape applications;

  • Accent
  • Shade
  • Mass Planting

Planting & Growing

Trompenburg Japanese Maple will grow to be about 25 feet tall at maturity, with a spread of 20 feet. It has a low canopy with a typical clearance of 4 feet from the ground, and is suitable for planting under power lines. It grows at a slow rate, and under ideal conditions can be expected to live for 80 years or more.

This tree does best in full sun to partial shade. It prefers to grow in average to moist conditions, and shouldn’t be allowed to dry out. It is not particular as to soil pH, but grows best in rich soils. It is somewhat tolerant of urban pollution, and will benefit from being planted in a relatively sheltered location. Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates. This is a selected variety of a species not originally from North America.
