Best uses

Great in small gardens and in difficult conditions, such as infertile clay soils. Showy yellow flowers in early spring add colour to native plantings.

Physical characteristics

A small evergreen shrub up to 4m that is relatively short-lived (4 - 7 years). Can be planted in difficult locations, such as steep banks, scrubby land and clay soils.

Flowers and foliage

Wrinkled, dark green leaves with hairy undersides. Yellow flowers from late winter to spring.

Preferred site

Grows in full-sun to part-shade. Prefers well-drained soils and does well in clay soils.

Preparation for planting

Best propagated from seed, which is slow to germinate. Prepare the planting site when soil is moist and easily worked. Plant when the soil is moist and warm in autumn, so that a good root system develops. Always choose healthy, well-grown plants and plant after autumn rains. Before planting, ensure the root ball is saturated and remove the planter bag or pot with minimal root disturbance. Trim any broken roots and plant at the same level as in the container. Dig a hole twice the diameter of the root ball, press in and water once planted. Make sure plants are watered well until established if planting in a drier period.

Maintenance tips

Apply mulch annually to help suppress weeds. Kūmarahou does not respond well to fertiliser. It can be prone to root rot so plant in sunny, well-drained sites.

Ecological and biodiversity benefits

Attracts invertebrates for birds like pīwakawaka to eat, and creates habitats for birds.
