Euonymus japonicus ‘White Spire’® adds a clean white brushstroke wherever the garden needs light and elegance. Its small glossy leaves combine green and grey-green tones with a broad creamy-white margin, building a dense, luminous column. That contrast keeps its interest through every season. Placed beside dark foliage or a simple pot, it brings out both its own fine detail and the character of the whole planting around it.
The upright growth adds a clear vertical line among plants that spread or form low tufts. Repeated along the front of a border, it brings cohesion; in a mixed pot, it provides a permanent centre around which seasonal flowers can change. The white margin combines naturally with silver, burgundy and deep green foliage.
Plantarium 2018 — Bronze award — ‘White Spire’ was recognised for its upright habit, stable variegation and distinctive ornamental value.
It was selected for a clean white edge, uniformity and upright behaviour.
The broad margin remains throughout the year and brightens the dark green surface.
Upright growth adds vertical emphasis without taking the width of a relaxed shrub.
Its white variegation is valued for uniformity and stability.
Why you will love it: it creates a luminous vertical accent wherever every centimetre of space matters.
Repeat it along a path, use it as a small low hedge, or make it the upright centre of a mixed pot. The white edge looks especially clear against a dark background.
In a line, allow crowns to approach gradually rather than compressing them from the start. Air around the foliage reduces problems during damp periods.
White and green combine with burgundy, clean blue and silver. Companions should share free-draining soil, sun to partial shade and moderate watering.
Sun to partial shade; in extreme heat, protect from strong afternoon sun.
Moderate watering when the surface dries, with free drainage.
Hardy to approximately −15°C when established in freely draining soil.
Harmful if eaten and not intended for edible use.
Abundant light keeps the crown dense. In hot climates, afternoon shade protects white sections from scorch.
Water deeply as the upper soil dries. In a pot, allow all excess to drain away.
It accepts different soil types as long as they drain. Do not bury the root collar deeply.
One light balanced application in spring is enough. Excess can loosen the upright habit.
If needed, shape during summer with small cuts. Do not repeatedly top it if vertical growth is wanted.
Remove any fully green shoot from its base, as it may grow more strongly than the variegated portion.
Keep moisture even in the first year so roots can extend before fast top growth is expected.
Fresh upright stems fill the narrow crown and carry the cleanest new white edges.
With minimal shaping it becomes a compact vertical element; grouped plants form a bright continuous line.
Several nearly vertical shoots arise from the base. Small elliptic leaves in opposite pairs make a dense, narrow crown.
White variegation remains throughout the year. Paler young tips stand out in spring, while the deeper green of mature leaves becomes more prominent later.
What to expect after planting: a steady increase in height and density without losing the limited horizontal footprint.
In August 2012, at his nursery in Sint-Oedenrode in the Netherlands, Theo Wouters noticed an unusual branch on Euonymus ‘Green Spire’. Within the green foliage, this branch had developed white variegation through a natural mutation. The parent’s upright habit was now combined with a much brighter leaf.
Propagation by softwood cuttings began at the same nursery in October that year. Successive generations and trials confirmed that the variegation and dense, columnar growth repeated reliably. The selection was named ‘White Spire’.
European protection EU 49713 and a bronze award at Plantarium followed in 2018, with Plantipp presenting the selection. US Plant Patent 31,872 was granted on 16 June 2020, naming Theo Wouters as inventor and Green Beheer B.V. as assignee. Today’s green-and-white column began with just one different branch.
The broad white border reflects a stable spatial arrangement of chlorophyll-bearing and chlorophyll-poor tissue within each leaf. Uniformity is judged across successive flushes because a sound clonal selection must repeat the pattern without erratic green reversions.
Leaves arise in opposite pairs and each successive pair rotates by about 90 degrees. This decussate phyllotaxis builds four repeating ranks along the shoot and visually reinforces the distribution of leaves around the shoot.
Six practical answers about position, watering and long-term growth.
Yes, variegation remains year-round, although intensity changes with light and leaf age.
Yes. The upright form suits restricted width, with room for air between crowns.
During summer if needed, using light cuts that preserve its vertical line.
It is hardy to about −15°C when established in free-draining soil.
White tissue contains less chlorophyll and may suffer in extreme afternoon sun or sudden drought.
Remove it at its point of origin because it is usually stronger and may alter the variegated appearance.
