Beni kagami
‘Beni kagami’ is a Japanese maple with red to purple foliage, with deeply cut and often glossy leaves that give an elegant silhouette. Spring starts orange-red to purple-red, summer deepens to a burgundy / purplish-brown, then autumn finishes with a very clear crimson red.
Character & interest
This cultivar combines strong colour presence (without being “black” all the time) with finely cut foliage, often described as glossy, which enhances a high-end look in low-angle light. The silhouette is that of a small tree that opens up over time, with shoots that may arch slightly.
Colours
-
Spring : orange-red to purple-red (shade varies with exposure).
-
Summer : burgundy / purplish-brown, sometimes a little greener in deeper shade.
-
Autumn : crimson red.
Habit & vigour
Tree-like habit, rather open / spreading with age. Steady vigour.
Indicative size
Order of magnitude: about 3.5 m after 10 years in good conditions, then a small tree that can reach 4–6 m (sometimes more depending on references and climates).
Exposure
Best results in gentle sun or bright partial shade. Good light helps maintain depth of red; in very hot situations, some afternoon shade improves foliage hold.
Origin & history
Japanese cultivar. The name is generally translated as “red mirror”.
