Standard tree/feathered
A less known term for two groups is standard tree. This is a wide definition for everything that has a tree-form (with a continuing main trunk). This can be a standard tree, but also a tree having side-branches from (or close to) the ground. We name these feathered trees. The difference will be explained by the measurements noticed.

Half standard (80-160cm Trunk)
A tree, shrub, or rose with a trunk of appr. 100cm (80-160 cm), followed by the crown. This form is available through all groups of plants. You can buy them in trees, shrubs, conifers and roses.

Multi-trunk (tree)
Multi-trunk means a tree/plant grown with multiple stems, often used with trees that grow naturally large. The term shrubbish is used as well, which is incorrect. The latter has a single stem growing out of the ground to be split higher. The visible difference is negligible though.

Shrub
These are plants that are branched between 0.2 to 3-4m after 10 to 15 years. If the species grows to more than 4-5m we call it shrubform of a tree. In that case they can be found under Trees > Shrub. We prefer to use the term shrubby tree.

Planting stock
Young plants/trees (often seedlings from woody crops) aged 1 to 3 years. These are quite inexpensive products of in between €0.20 to €1.50. Mainly sold with bare roots starting from half October until half April, depending on weather circumstances. Potted planting stock is becoming better available, despite the higher costs.

Used mainly as landscape planting and for bigger gardens.

Used as starting material for tree nurseries.

Columnar (pruned)
Is not growing columnar by nature, but has been cut. The conditions are long and narrow, it will become a cone otherwise.

When lacking cutting or shaving the tree/plant will continue growing to its original form.

Blockform (pruned)
Branches grown or cut into a block shape. Possibly on a stem.

Block to us means having 6 equal sides. In other cases we call it a cube.

In case you don't cut or prune, the tree or plant will return to its original/natural form.

Cylindrical (pruned)
Tree or shrub, grown in a cylindrical form (pruned)

Beam-form (pruned)
Branches grown as a cube (pruned)

Conical (pruned)
Cut in a cone-form, not to be confused with a columnar and pyramid. The cone starts broad and ends in a point (tapered).

Pyramidal-shaped square (pruned)
Square cut like a pyramid. Not to be confused with a cone or column form.

Spheriform (pruned)
Has been grown into a sphere by means of cutting. Buxus and conifers are good examples of species suitable for this way of shaping.

If you don't cut the tree or plant it will return to grow in its natural form.

Espalier
Espalier means the branches are supported in a screen of different floors (levels), starting at a particular height, but other variations are possible.

As soon as the tree has a screen with the size of appr. 200-225cm, starting at the ground, we tend to talk about a screen hedge.

For more on the different sizes, please have a look at the pictures used in the different categories.

Parasol - Horizontal espalier
The branches of the tree form a artificial parasol. Well known is the parasol-sycamore, but there are many more variants. Often trees are used that have leaves with extra ornamental value, mostly large-leaved species.

Screen hedge
Branches are supported in floors from the bottom up, in a screen. A ready-to-place hedge is a hedge supported to a screen. The great advantage of this system is the possibility to keep the hedge quite narrow.

Arch-shaped
Has been supported to an arch (roses/beeches)

Perennial
Plants that are winterhardish and do not lignify. They often bloom richly and are used in borders often.

Low stemmed (30-60cm Trunk)
This term often applies to fruit trees, for which a weak-growing root-stock has been used. A trunk of about 50cm, followed by the crown. The term low stemmed is often used in relation to fruit trees. Not to be confused with a shrub-form, as these are not attached to a weak-growing root-stock.

Climbing plant
Climbs a wall, fence, or something else.

Shrubby tree
This is a shrub that has been made out of a tree that easily grows up to 4-10m, branching near the ground. Not to be confused with a low stem, because that one has been put on a weak growing root stock, or a shrub, which don't grow much higher than 3-4m. This form is better known in the nurseries than to private customers.

Bonsaï-shaped
Bonsai-form of a shrub, half-standard or standard. The number of arms (the larger branches) is usually mentioned as well. Examples are olive trees, buxus consisting of multiple spheres, and more free forms where the arms have been cut or pollarded. In the column Trunk Height it is possible to see the height at which the first arm starts. Under Height you can see the total height of the plant or tree, under Crop the development of the spheres or pollard-forms is noticed. The Miscellaneous column shows if it applies to a shrub, half-standard, multi-trunk or standard tree.

Pollard

Olive trees
The most popular olive tree (Olea europeae) is available in many kinds. In the open as well as used as a patio plant, the olive tree will quickly add a Mediterranean touch to your environment. The Olea europeae is winter hardy till minus 15°C. Below this temperature olive trees have to be protected against the cold.
