Doom and bloom

Dunedin Botanic Garden rose and herbaceous collection curator Linda Hellyer removes the heads of spent dahlias in the herbaceous border of the garden.

The flowers produce seeds after they begin to wilt, which detracts from the plant's beauty and may shorten the blooming season.

Removing, or deadheading, the spent flowers will help the plant to continue blooming well into the autumn.
