Cultivation Details

A fairly easy plant to grow, requiring a sunny position in any reasonably fertile, well-drained soil[]. Tolerant of strong winds, even those carrying salt[]. Often grows on sand dunes in New Zealand[].
This species is not hardy in all parts of Britain. It should be tolerant of light frosts, but prefers an essentially frost-free environment[].
A long-lived plant[].
Members of this genus are rarely if ever troubled by browsing deer or rabbits[].
A dioecious species - both male and female forms must be grown if fruit and seed are required[]. The inflorescence on the male plant is rather erect whilst it has wide spreading branches on the female[].

Edible Uses

None known

Medicinal

The seed heads are astringent and have been used on fresh wounds to stop bleeding. Other medicinal uses include the treatment of diarrhoea, kidney complaints and burns[].

Other Uses

Plants can be used to provide shelter in exposed conditions, to minimise stream bank erosion, and can be planted to help maintain the stability of sand dunes[].
Maori used the toetoe leaves to make baskets, kites, mats, wall linings and roof thatching[]. It was also used to make containers to cook food in hot springs. The flower stalks were also useful - as frames for kites, and in tukutuku panelling[].

Propagation

Seed - surface sow early to mid spring in a greenhouse. The seed usually germinates in 2 - 3 weeks at 15°c. Keep the soil moist. The seed has a short viability[]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts.
Division in late spring[]. It can be very difficult to obtain divisions from this plant because they tend to be very large and to be very close to the main clump. We have found it best to use a sharp spade to cut into the main clump and break off the divisions. These are then potted up in light shade in a cold frame and are planted out once they have rooted well and are in active growth.
