Synonyms

Senecio kirkii var kirkii Hook.f ex Kirk; Urostemon kirkii var. kirkii (Kirk) B.Nord., Senecio neo-zeylandicus Druce, Senecio glastifolius Hook.f. nom. illegit.

Distribution

Endemic to the North Island. Locally scattered throughout.

Habitat

An epiphyte of lowland to lower montane forest, sometimes terrestrial.

Features

A spring flowering, usually epiphytic shrub to 1.5 m tall with purple stems and grey bark developed on old wood. Leaves 40 to 100 by 20 to 40 mm, fleshy, variable in shape, usually toothed in upper third, hairless, upper surface pale to dark green, often tinged maroon, undersides paler. Flowers 30 by 40 mm diameter, borne in dense inflorescences of 3 to 20 flowers, the individual daisy-like flowers have white petals (rays). Fruits dry, windborne, dandelion structures.

Similar Taxa

A very distinctive species. However, because it is usually epiphytic and so often well out of reach, plants could be confused with the epiphytic Pittosporum kirkii and P. cornifolium. These pittosporums have leathery leaves, non-daisy like flowers and round fruits which split to reveal hard black seeds embedded within sticky gum.

Flowering

August to October

Flower Colours

White,Yellow

Fruiting

Propagation Technique

Easily grown from fresh seed and semi hardwood cuttings but, as a rule, difficult to maintain in cultivation.

Threats

This plant is intolerant of browse and targeted by possums, goats and deer.
