Probably only cold hardy to -5☌ (23☏) and not suitable for windy gardens as the leaves are easily damaged.Palm leaves are an incredible material that has been used by humans for thousands of years. Washingtonia filifera (Washington palm): Tall fan-palm, fast growing and not suitable for a small garden. Slow growing the trunk may grow to 5m (16ft). Trithrinax campestris (Caranday palm): Fan-shaped, blue-green, wind resistant leaves. latisectus from north-east India and has broad, glossy, dark green leaves. wagnerianus has stiffer, more wind tolerant leaves. It is tolerant of heavier clay soils and some shade. Withstands temperatures of -15☌ (5☏) or below if sheltered. This is the one species of palm that can be grown widely in the UK, though the leaves may be damaged by high winds in cold, northerly, exposed sites. Trachycarpus fortunei (Chusan palm) AGM: Large fan-shaped leaves. Most suitable in a sheltered well-lit south- or west-facing position. Cold tolerant to -12☌ (10☏), but requires hot summers. Sabal minor (dwarf palmetto): Slow, low-growing fan palm to 60cm (2ft) with large stiff blue-green leaves. Most suitable in sheltered south- or west-facing positions. Very slow growing eventually forming clumps of attractive deep-green leaves to 1m (3¼ft). Rhapidophyllum hystrix (needle palm): Very cold tolerant fan palm to -15☌ (5☏), but it requires hot summers. A relatively fast-growing feather palm for a sunny, well-drained spot. Phoenix canariensis AGM (Canary Island date palm): Hardy to -8☌ (18☏). In mild areas, it can develop an erect trunk to about 5m (16ft) but is very slow growing. Jubaea chilensis (Chilean wine palm): Hardy to about -14☌ (7☏), but it will not tolerate cold, windy situations. It is also suitable for heavier clay soils. One of the hardiest feather palms, it can be grown outdoors in sheltered gardens where it may tolerate -10☌ (14☏). Hardy to about -8☌ (18☏) in a well-drained, sheltered sunny spot.īutia capitata (jelly palm): Relatively slow growing with attractive arching green-blue leaves. argentea from the Atlas Mountains in Morocco has attractive silvery-blue leaves.īrahea armata (Mexican blue palm): Attractive, slow-growing fan palm with stiff pale blue leaves. It is suitable for heavier clay soils and partial shade. It is wind resistant and will tolerate -12☌ (10☏) or lower. Where containers are left outdoors, ensure the pot is bubble-wrapped to prevent frost damage to the roots.įor more ideas on choosing palms for the garden, see our Find a Plant tool.Ĭhamaerops humilis (dwarf fan palm) AGM: Forms clumps of fan-shaped leaves, up to to 2m (6½ft) tall. Palms grown in containers should also be protected or brought under cover for the winter. Where cold winters occur, prepare plants with a protective wrapping. Prolonged winter frosts and cold winds damage leaves and may kill the central growing point. Winter protectionĪs the palm stems thicken with age, the plants become more tolerant of lower temperatures. Palms grow slowly and need adequate space as they do not compete well with surrounding plants and most are not tolerant of shading. Planting into the centre of this mound will keep at least some of the roots above the saturated soil in winter. On heavier clay soils prone to winter waterlogging, thoroughly cultivate a wide area and throw up the soil into a low mound 25cm (10in) high. Choose a well-drained spot in a sheltered position as few palms tolerate windswept locations Plant in mid-spring to allow time for the palm to establish before winter.Hardy palms that will be planted out in the garden should initially be grown in containers and brought under cover (ideally into a frost-free greenhouse) during winter until well rooted in at least a five litre pot.Palms can be grown in containers of John Innes No 3 compost.As a result, the temperatures quoted are a general guide only – and the term hardiness is applied to mature specimens as young plants are more liable to being damaged by cold weather. However, plants that are in exposed positions, in containers or wet at the roots will be more liable to winter damage. Some hardy palms will survive winters in much of lowland Britain in sheltered gardens with favourable local conditions. Malvern Autumn Show - 27-29 September 2024.
