6 foot tall loquat tree

Eriobotrya japonica (Japanese Loquat or Medlar)

The Loquat is a small evergreen winter hardy tree with impressive large dark green foliage giving an almost tropical or exotic look to your garden. It produces small white flowers and fruit in some milder parts of the UK but is mainly grown for its large (8 inch long) leaves. The RHS hardiness rating is H3 which is down to -5°C so depending where you are in the UK may suffer some leaf damage in cold winters. The Loquats pictured are located in the Fens but in a city location and survived the cold temperatures of December 2010 where temperatures regularly dropped to around -6°C to -8°C during that month.

The leaves can reach a foot long (30cm).

Large tropical looking foliage

The Loquat tree is not commonly grown here in the UK but it is a plant that you cannot easily mistake if you do spot one growing in someones garden. It is grown for its large long tropical looking foliage that can reach a foot long, about 30 centimetres. It is evergreen and in the UK can survive down to about -10°C (RHS say H3, -5°C) with some frost damage to any tender new growth. It will happily spring back from any damage. A sheltered shady spot will encourage larger leaves.

It makes a great small tree and tends to remain quite small and compact judging by the established specimens growing in England. In their native China and where they are commercially grown for their fruit where it is warmer they will grow to their full size, possibly up to 9 metres but about 4 or 5 metres in the UK.

Loquat flowers late winter to early spring.

May flower but doesn't often develop mature fruits

Flowers late winter to early spring but does not commonly produce flowers or fruit in many parts of the UK. They are more likely to flower and produce edible fruit in the southern parts or England or micro climates such as London.

Young plants can flower from about 3 to 5 years of age but more likely to do so after 5 years. As it flowers in the winter you will need a mild winter for the fruit to survive. The flowers and fruit can take some sub zero frosts and survive to produce fruit.

Loquat hardiness in Britain

As previously mentioned E. japonica is hardy and evergreen when grown in this country. It can take temperatures down to about -10°C with reports from gardeners that their trees have survived periods at -15°C unscathed. Even young plants will survive outside throughout winter although they become hardier as they get bigger.

How big is Eriobotrya japonica?

This small tree can grow to 10 metres or so but is more likely to be seen in the UK at about the 5-6m mark as pictured. It makes a good specimen for even relatively small gardens and can easily be pruned to maintain a smaller size. A sheltered warm spot is ideal to give it some protection especially if you live in a rural location.

lighter green new leaf growth
New leaves appear light green almost white.

Eriobotrya deflexa 'Coppertone'

Although not grown commercially in the UK for its fruit there are a number of named cultivars grown around the world that a more prolific fruiting varieties. If you buy a UK grown specimen it will most likely be seed grown or from a cutting of a seed grown variety.

An alternative if more tender is the Coppertone or Bronze Loquat with its copper coloured new growth compared to the light green almost white of the standard variety. Think Photinia meets Loquat and you have a handsome but less hardy variety which at best may be able to take short periods of sub zero temperatures. Worth growing if you live in London or the South West but it may struggle further North.
