Start with the role of the tree
Tree form should respond to how people will experience the space. An arrival courtyard may need one memorable specimen, while an avenue needs repeatable clear trunks and crowns. A shaded gathering area may prioritize broad canopy and lower visual mass.
Broad-canopy specimen
This form is selected for presence and shade. Compare crown spread on two axes, crown depth, balance, branch structure and the relationship between crown width and overall height. Confirm whether the existing canopy can be retained through preparation and transport.
Upright or clear-trunk form
An upright profile can suit circulation routes and more constrained spaces. State the required clear trunk, crown width range and acceptable taper. Do not rely on height alone, because two trees with the same height may have very different usable clearance.
Multi-stem and banyan-style character
Multi-stem trunks and aerial roots create a more established, sculptural appearance. Individual photographs are important because character cannot be fully expressed through one girth number. Define whether irregularity is desired or whether the group needs visual consistency.
Repeatable project form
For repeated planting, specify a range rather than expecting identical trees. Agree minimum and maximum dimensions, crown balance, clear trunk, acceptable trunk variation and how the group will be sampled.
Translate design language into sourcing criteria
Words such as mature, iconic or lush are useful direction but not complete buying specifications. Pair them with measurable dimensions, reference views, mandatory features and acceptable variation.
Frequently asked questions
Can different forms be combined in one project?
Yes. Feature trees, shade trees and repeated groups may use different acceptance rules, but each group should be clearly identified in the BOQ.
Should the buyer specify a Ficus species first?
The botanical requirement matters, but form, site constraints and import feasibility should be considered together rather than in isolation.
