Symmetry is one of the oldest tools in interior design and one of the most misunderstood. A great deal of received wisdom about matched planting is either half-true or flatly wrong, which is why so many people either avoid pairs altogether or use them where they backfire. Here are the beliefs I hear most, and what actually holds up in a real room. The short version is that symmetry is far more flexible, and far more forgiving, than its reputation suggests — and artificial trees are ideally suited to it, because you can buy two that genuinely match and know they will stay matched.
Myth: symmetry always looks formal and stiff
A mirrored pair reads as calm, not cold — the stiffness people fear comes from the shape of the plant, not from the symmetry itself. A pair of loose, natural forms flanking a fireplace feels settled and relaxed. It is clipped geometry that reads formal, and even that can be softened by the setting. The device is neutral; the foliage sets the tone. A Artificial Bay Trees Natural Straight Trunk Topiary Bay Laurel Ball Tree at 90cm and £34.99, bought as a pair, sits happily either side of a hearth in a period or a modern room.
Myth: the two plants must be identical
Near-symmetry does most of the work and forgives far more. Two plants of the same family and roughly the same height read as a pair even if the individual branches differ, which of course they always do with anything natural-looking. What the eye checks is the overall mass and silhouette, not a leaf count. Two 90cm Podocarpus Double Ball Topiary Tree Artificial pieces at 90cm and £49.99 each will pair convincingly without being a perfect match.
Myth: symmetry belongs only at the front door
Flanking an entrance is the classic use, but it is far from the only one. Matched planting frames anything with a centre line: a chimney breast, a bed, a run of bookcases, the mouth of a wide opening between two rooms. Indoors it calms a busy elevation; outdoors it dignifies a doorway. A weatherproof 120cm Artificial Bay Tree Laurel UV Resistant Outdoor Topiary at 120cm and £79.99 is rated UV-stable, so a pair can hold a porch through the seasons.

Myth: you should never break the mirror
Perfect symmetry can tip into lifeless, and a deliberate small asymmetry often reads as more confident. Pair two matched trees, then let one carry a slightly fuller canopy or sit a touch further forward. The eye still registers a pair, but the arrangement feels arranged by a person rather than a machine. This is the trick that stops a formal scheme looking like a hotel foyer.
Myth: only clipped topiary can do it
Any strong, repeatable shape works. A pair of 120cm (4ft) Artificial Boxwood Buxus Ball Topiary Tree pieces at 120cm and £54.99 gives a crisp ball on a stem, but two soft 90cm Artificial Deluxe Olive Tree trees at 90cm and £50.99 create just as strong a symmetry with a looser, Mediterranean feel. Match the character of the pair to the room. Compare shapes in topiary trees and olive trees.
Myth: symmetry only suits large, grand rooms
Scale has nothing to do with it. A pair of small plants either side of a modest fireplace, or flanking a narrow console in a hallway, brings the same steadying order that a grand pair of trees brings to a ballroom. In a small room symmetry can actually help, because it imposes calm where clutter would otherwise creep in. The pieces simply need to be sized to the setting: a compact pair on a mantelpiece, a taller pair on the floor. What matters is the mirror, not the magnitude.
Myth: matched pairs are twice the risk
Buying two of something feels like doubling down, but symmetry is actually the most forgiving arrangement there is, because the two halves prop each other up. A single statement plant has to be perfectly placed; a pair simply has to be even. If you are nervous about a scheme, a mirror is the safest move, not the boldest.
What reliably works
- Match by silhouette and height, not by counting leaves.
- Keep the pair on a genuine centre line — measure it rather than eyeballing.
- Let the foliage, not the placement, decide how formal the result feels.
- Introduce one small, deliberate difference to keep it human.
Because a pair only works when both halves are truly even, it is worth ordering and standing them together before committing: UK delivery is free over £30, and the thirty-day returns window gives you time to check the match in your own light. Palms make an elegant looser pair too, gathered in palm trees.
