The luculia was introduced to the west by plant hunter, Ernest 'Chinese' Wilson. It occurs naturally on lightly wooded hills in the lower Himalayas to Yunnan, where apparently it grows in large forests. In the home garden it's hard enough to get one luculia to grow, let alone a forest of them, but they are definitely worth the effort. They belong to the family Rubiaceae, along with their relatives the gardenias. One of the things these plants have in common is wonderfully scented flowers, in fact the perfume of the luculia is somewhere between a gardenia and a vanilla fragrance. In our segment Don looked at the most popular species, Luculia gratissima, but there are four others including the white flowering Luculia grandiflora.

Plant details

Common name: Luculia

Botanic name: Luculia gratissima
The genus name, Luculia, is the Latinised form of the Nepalese name, Luculi Swa. The species name, gratissima, is Latin for 'most pleasing'.

Description: Luculias are evergreen shrubs with rounded, often irregular growth habits. In the wild they are said to reach 6 metres (20'), but in cultivation they are usually around the 3 metre (10') mark. In winter, fragrant pink flowers appear in large heads up to 20cm (8") across.

Best climate: Mountain zones where the frosts aren't too severe, or cooler coastal areas of Australia. Protect young plants from frost.

Good points:

The flowers are magnificent. Not only do they look beautiful but they have a lovely perfume.

Downside:  difficult to grow susceptible to Phytophthora root rot flowers often ruined by rain and wind

Care: Luculias grow well in a semi-shaded position (or a spot with protection from hot afternoon summer sun). A free-draining coarse soil with added organic material is best. They like a cool root zone, so keep the plant mulched. Do not let the soil dry out. Luculias resent root disturbance and don't like to be transplanted. During prolonged periods of heavy rain, spraying the foliage with a phosphorous acid product such as Yates Anti Rot may help prevent root rot. Shoots that have been damaged by frost can be cut back to a pair of healthy leaves or buds in late winter to early spring, when the chance of frost is past. A light prune to remove spent flowers at this time will also help to shape the plant and keep it bushy. Luculias benefit from the occasional application of a small amount of lime, except in areas such as Adelaide or Perth which have alkaline soils.

Getting started: Luculias are also available at most nurseries in areas where they grow, while they are in flower (usually from late autumn to July). They cost around $24 for 200mm (8") pots. Luculias can be propagated from seed or semi-hardwood cuttings in summer (semi-hardwood cuttings are tip cuttings that have just started to harden off). Yates Anti Rot is available at most nurseries, and costs about $15 for 500ml.
