Threatened Plants Garden
Kaipatiki
Project’s threatened plant garden showcases threatened plants from the North
Shore and Auckland Regions.
You are most welcome to view the gardens any time from Saturday 10-3pm or
during the week from 9-4.
Perhaps you would like to plant these in your garden also to help preserve our
threatened native plant species?
Please view our gallery below to learn more.
Clianthus

HABITAT

|
|
PRESENT
DISTRIBUTION IN NZ
|
Native
to northern areas kakabeak originally occurred at small island and
coastal sites from the Bay of Islands to Tolaga Bay on the East Coast as
well as inland at Lake Waikaremoana. It is now extinct at a number of
sites. The white-flowered variety originates from Tiniroto Cliffs, south
of Gisborne.
|
|
THREATENED
STATUS
|
THREATENED
NATIONALLY
Some
of the biggest threats to C.puniceus are aphids and other pest insects;
and witches broom
|
| ADVICE
ON GROWING |
Kakabeak
has a sprawling form up to 2m tall. Suitable to espalier/climber. Needs
protection from heavy frost. Apart from its attractiveness to slugs,
snails and other pests a serious problem it faces is a witches’ broom,
which causes deformed, gall-like growths and should be pruned off when
first seen. The flowers are bird pollinated. It can be cultivated from
seeds or cuttings. |

MILKWEED
- NZ SEA SPURGE – SHORE SPURGE – MAORI SPURGE
Waiūatua
- Waiū-o-Kahukura
|
HABITAT
|
This
is a coastal plant, which grows in beach sands, open scrub and
amongst rocks near the water
|
|
PRESENT
DISTRIBUTION IN NZ
|
It
occurs on both main islands as well as on Stewart Island and the
Chatham Islands. It
is also native to Norfolk Island. Numerous colonies are known
but most are small and often extend only over a few square
metres. The largest populations are probably found at the Chalky
Inlet area of Fiordland.

THREATENED
STATUS
|
THREATENED
NATIONALLY |
| ADVICE
ON GROWING |
Grows
to height of 30-70 cm. Creeping rhizome. Poor, very well drained
soils and hot, sunny situations suit it to perfection. Sap is
thick and milky. Site pioneer/coloniser. Used for sand dune
restoration. Propagation best by division or cuttings. |

HABITAT
|
A
wide range of habitats but mainly coastal areas
|
|
PRESENT
DISTRIBUTION IN NZ
|
Found
rarely in coastal areas from North Cape to Coromandel.
|
|
THREATENED
STATUS
|
THREATENED
NATIONALLY
F.
procumbens
has declined dramatically in the wild, due to:
- encroachment
of habitat by tourism and development;
- trampling
and grazing by cattle and other animals;
- drifting
sand and erosion;
- encroachment
by kikuyu and buffalo grass;
-
plants
can be either male, female or hermaphrodite – some
colonies have plants of only one sex and cannot breed.
|
| ADVICE
ON GROWING |
A
groundcover, that scrambles over rocks and low walls putting
down roots as it goes. It is best in partial shade but can
tolerate full sun and coastal conditions. Propagation by seed,
rooted divisions or cuttings. |

1
plant in left in the wild in Tasman Valley, Great Island in the
Three Kings Islands. |
|
THREATENED
STATUS
|
THREATENED
NATIONALLY
Despite
the fact that this is now grown in many gardens in New Zealand,
once the original plant that is left in the wild dies, T.speciosa
as it naturally occurs will be considered extinct.
|
| ADVICE
ON GROWING |
All
of the plants found in gardens today have been propagated from
the one plant left in the wild.
This plant is a woody climber and grows in sun or
semi-shade in any reasonable soil but requires strong support.
It is frost tender and can be propagated from seed or cuttings.
Flowers late autumn to early winter and attracts Tuis. |
