The interest here is in the transition from one frond to the next.
Form & character
Young fronds may show coppery or pink tones. Broadly oval, divided blades form a compact clump. The RHS lists the species as semi-evergreen, so winter foliage depends partly on conditions.
A place to grow
Choose a cool, moist position with light shade and shelter. Water well during establishment, even where an older plant could eventually tolerate drier soil.
A detail to notice
Photograph the same plant over several weeks. Keep the exposure similar so that changes in lighting are not mistaken for changes in the foliage.
