Description

Helichrysum lanceolatum is a member of the daisy family (Asteraceae) which is the most widely distributed and successful flowering family of plants in the world. H. lanceolatum is among a significant number of New Zealand Helichrysum species, nine of which are endemic to New Zealand. Many of these species grow into shrubs or trees and are woody, thus being termed tree daisy. The New Zealand endemic Helichrysum species are heterogeneous, meaning they are not uniform and have distinctive traits.

 

Helichrysum lanceolatum is a tangled, much branched, interlacing shrub, growing up to 3 m in height. It has light brown bark with slightly grooved branches and alternate leaves. Young branchlets are finely hairy and evolve from dark brown to lighter brown with dark streaks as the wood thickens and ages. The leaves are green/grey in colour and are pointed or rounded, smaller on flowering branches, and are arranged alternately along branches. The upper surface of the leaf is smooth, the tip is silver, and the underside is grey and downy.

The flower heads consist of abundant clusters of very small, up to 1 cm diameter, creamy white, scented flower heads. These can be confused with the furry galls induced by Cecidomyiidae larvae. The composite or compound flowers, resembling a single flower, are made up of multiple small flowers bordered by rows of discreet bracts; the whole structure termed a capitulum.
