Ceratopetalum ‘Johanna's Christmas’

cultivar

Family: Cunoniaceae

This cultivar is a dwarf form of Ceratopetalum gummiferum.

It is a dense shrub to 1.5m tall x 1.5m wide.

Registered with ACRA by Brian and Carol Roach of Westleigh, Sydney on 14 Jan 2004.

The leaves of this species are compound with 3 leaflets (trifoliolate) and arranged in opposite pairs, light to mid-green in colour. New growth may be bronze-red. Each leaflet is to 4 cm long by about 1 cm wide and narrowly-lanceolate with regular shallow teeth.

The white flowers appear between October and January. Flowers of this genus have very minute petals or petals may be absent. In this species, the 5 petals are very short (less than 5 mm), with divided tips.

The 5 sepals (calyx) play the role of the petals. They start off white in about October, and then enlarge, up to 2 cm long and turn bright red, surrounding the developing nut (fruit) around Xmas time. The flowers are arranged in terminal cyme-like groups.

In the garden

In a garden situation, it is at its best in full sun growing in a moderately moist soil.

Providing regular watering will give a good, and long flowering season.

Can be used as a feature shrub in a sunny well drained position in the garden or as a pot plant for courtyards.

After flowering, it needs a light trim back behind the spent flowers.

Feed with a good native fertiliser in spring.

Can be occasionally troubled by a mite which deforms new growth.

They do make an ideal pot plants in a large-tall pot.

It is advised to only grow it if you can water it well.

Propagation

From cuttings which can be difficult.
