Kentia Palm

Howea forsteriana

Kentia Palm is a long-lived, evergreen palm that brings an upright framework and arching dark green fronds to sheltered interiors and mild outdoor landscapes. At up to 30 feet tall and 12 feet wide, it reads as a vertical focal point rather than a filler plant. Use Howea forsteriana where its canopy can rise above lower planting without crowding doors, windows, or circulation.

Placement and use

Place it as a specimen beside a patio, pool edge, wall, or broad path, keeping the crown clear of places where fronds would brush passersby. Its slow growth makes it useful in a composed planting that should hold its structure for years, rather than a bed that needs quick screening. In containers, give it a stable, generously proportioned pot and position it in a shaded outdoor sitting area or a roomy indoor corner with open headroom.[1][2]

Spacing and mature footprint

Set multiple Kentia Palms 10 feet apart, center to center. That interval allows the 12-foot mature crowns to visually overlap slightly while preserving enough separation for each palm to retain a distinct silhouette. Keep the planting center well back from a narrow walk, fence, or building edge, and reserve an access strip so older fronds can be reached without stepping through neighboring plants.

Three plants set 10 ft apart, center to center; shaded circles show the 12 ft mature spread.

Sun, water, and soil

Use partial shade, especially where overhead cover or filtered light protects the fronds from harsh direct sun. Keep moisture moderate: water deeply enough to moisten the root zone, then avoid leaving the soil continually wet. A well-drained, humus-rich mix suits containers; outdoor sites should also drain freely while holding some organic matter.[1][2]

Seasonal notes

This palm keeps its foliage year-round, so its canopy remains part of the plan in every season. Indoor plants need less water during winter than during active summer growth. In cold-winter regions, treat it as a permanent interior or protected container specimen rather than assigning it a year-round place in an exposed bed.[1][2]

Planning caveats

Allow for the long reach of individual fronds when placing furniture, gates, and paths nearby. Avoid a location that receives intense direct sun through glass or sits in a persistent draft. A single plant develops more freely than several crowded together in one pot, so grouped nursery plants are best given extra room or treated as a deliberately temporary composition.[1][2]
