Cryptomeria japonica 'Monstrosa'

Monstrosa Japanese cedar

Unusual, contorted branchlets and crinkled needles give Monstrosa Japanese cedar a distinctive texture. The green evergreen crown begins conical and can become rounder with age. Unlike the dwarf Monstrosa Nana selection, this is a substantial tree, best placed where its developing outline has generous room.

Landscape use & tree form

Form: Initially conical to columnar; rounder with age
Use: Evergreen specimen or focal accent.
Growth rate: More vigorous than Monstrosa Nana (cultivar study); growth varies by site.

Resistance & tolerances

Deer: Species is listed as resistant to deer damage, not deer-proof.
Drought: Established species trees tolerate dry periods, but water during prolonged drought; dwarf and container plants need closer moisture monitoring.
Wet soil: Prefers moist soil with good drainage.

Resistance is not a guarantee; deer and rabbits may browse any plant.

Seasonal interest

Foliage: Evergreen; contorted green growth, with winter bronzing reported in the eastern-US cultivar study.
Cones: Small woody cones; species cones and fallen foliage are not usually a significant litter problem.

Growing & care

Site: Prefers rich, acidic soil; generally needs little maintenance.
Pruning: Usually little shaping is needed. If necessary, shorten stray young shoots to a leafy side branch in early spring, retaining the cultivar's natural outline.
Soil: Rich, slightly acidic, moist but well-drained soil.
Issues: Allow air circulation; leaf spot and blight can occur. Monitor mites in dry weather.
