Eucalyptus Leucoxylon (Subspecies Megalocarpa.) – is an excellent small gum tree with large red flowers through autumn and winter with large decorative fruits up to 2cm long. It usually grows to between 6 and 10 metres high in its native habitat, with a short trunk and a spreading crown, but probably smaller if you can find a place to grow it in the UK. It is a very hardy red flowered form suitable for most soils and climates including costal sites and sand. Capable of withstanding frost down to about minus 7°C it makes an excellent ornamental tree for a sheltered light frost location.
