Mediterranean fan palm

Sun

Full sun is best; tolerates light shade but grows more slowly and less densely.

Water

Water regularly during establishment, letting the surface soil dry between waterings. Established plants tolerate drought; container plants need more frequent watering.

Soil

Well-drained sandy, gravelly or loamy soil; tolerates alkaline conditions. Avoid heavy soil that stays wet in winter.

Height

6-15 ft (1.8-4.6 m)

Spread

6-10 ft (1.8-3 m)

Flowers

Small yellow flowers in dense clusters among the leaf bases in spring to early summer; female plants may produce yellow-brown to reddish-brown fruits after pollination.

Foliage

Evergreen. Stiff, deeply divided green to grey-green fans on leaf stalks armed with sharp spines; trunks retain a covering of fibres and old leaf bases.

Growth rate

Slow

• Plant in spring after hard frosts, in a sunny position sheltered from cold winds.
• Water deeply through the first growing season, allowing the surface soil to dry between soakings.
• Use a modest application of palm fertiliser in spring if growth is weak or the soil is poor; avoid heavy feeding.
• Keep mulch clear of the trunk bases and growing points.
• In colder areas, protect the crown with breathable fleece during severe freezes and remove it when conditions improve.
• Use a container with drainage holes and move it to a bright, frost-protected position where winters exceed its tolerance.

Pruning. In late spring or early summer, remove fully brown fronds with clean tools, leaving healthy green leaves in place. Wear thick gloves and eye protection, and remove unwanted basal shoots only if you want a more open clump.

Spring

Plant or repot once hard frosts have passed, keeping the palm at its previous planting depth.

Spring

Feed lightly if needed and check container drainage.

Late spring

Remove dead fronds and assess winter damage; do not cut into the central growing point.

Summer

Water young and container-grown plants during dry spells, and inspect leaf undersides for pests.

Autumn

Reduce watering as growth slows and clear debris that traps moisture around the crown.

Winter

Protect during severe freezes and keep containers sheltered from persistent rain and freezing winds.

• Use as an evergreen focal point in a sunny gravel garden with lavender, rock roses and ornamental grasses.
• Plant in a broad raised bed to provide architectural foliage where winter drainage is otherwise poor.
• Grow in a large container on a sunny terrace, leaving room around the spiny leaf stalks.
• Group with other drought-tolerant plants in coastal or Mediterranean-style gardens for contrasting leaf shapes.

Garden styles it suits: Modern Mediterranean, Architectural minimal, Dry gravel garden, Coastal, Desert / xeriscape and Modern courtyard.

Plant it with: Lavender, Rock rose, Rosemary, Santolina, Red yucca and Blue fescue.

Wildlife: Flowers provide pollen for visiting insects, and a mature clump offers shelter for small animals. Its main garden value is structural rather than as a major wildlife food plant.

• Root or crown rot in waterlogged soil: improve drainage, reduce watering and keep debris away from the crown; severely rotted plants may not recover.
• Scale insects on leaves and stalks: wipe off small infestations and use a labelled horticultural oil where appropriate, following temperature restrictions.
• Spider mites, especially under cover: look for fine webbing and pale stippling, rinse leaf undersides and use a labelled treatment if the infestation persists.
• Frost injury: shelter young plants and protect during severe freezes; wait until late spring to remove damaged foliage so surviving growth can be assessed.

Not known to be toxic to cats, dogs, horses or people. The fruits are not recommended for eating. Sharp spines along the leaf stalks can cause painful puncture wounds, so keep it away from narrow paths and play areas.

• Windmill palm (Trachycarpus fortunei)

  Usually forms one taller, upright trunk rather than a suckering clump, and its leaf stalks lack the large, sharp spines of Mediterranean fan palm.

• Lady palm (Rhapis excelsa)

  Has slender, cane-like stems and leaves divided into fewer, broad segments with blunt or ragged tips; its leaf stalks are not armed with large spines.

Chamaerops comes from Greek words meaning 'low shrub', while humilis is Latin for 'low-growing', referring to the palm's usually short, clumping habit.

Propagation. Raise from fresh seed in a warm propagator; germination can be slow and irregular. Basal suckers can sometimes be separated in late spring if they have their own roots, but unrooted shoots rarely establish.
