![]() 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.

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.
