Soft silvery foliage, pretty flowers and an easy-going nature make Geranium traversii a great garden plant.

This low-growing perennial herb is one of New Zealand's largest geraniums, and is a native of the Chatham Islands, occurring on all the main islands of this group.

Its natural habitat is coastal cliffs, sand dunes and rock crevices.

The colour of the foliage is because of a dense covering of silvery hairs on the stems and leaves.

This makes it a lovely subject for mass planting as a filler plant among shrub borders, providing a foil for a range of foliage forms and colours.

Geranium traversii will thrive in most garden situations.

It prefers full sun and good drainage and is an excellent rock garden subject.

It is one of the few Chatham endemics which are relatively easy to grow throughout the country.

Although generally pink in cultivation there are also white-flowered forms of this species and very rarely a light purple. The flowering period is long, October to March (peaking in summer), another bonus with this bonny wee native. This species will self-seed readily.

In the hebe border of the native collection is a patch of Geranium traversii. This is just starting to flower and can be seen on the path side of the border next to the daffodil lawn in the upper garden.
