What to Grow, Where, and Why
Dry, hot environments present challenges like low soil moisture, intense sun exposure, and high temperatures. Native plants adapted to these conditions often have tough, drought-resistant foliage, deep root systems, and growth habits that minimise water loss, making them perfect for sustainable landscaping and restoration in dry areas.
What Makes Dry, Hot Sites Unique
-
Climate: High summer temperatures, low rainfall, and strong sunlight.
-
Soil: Often sandy, rocky, or well-drained soils with low organic matter.
-
Water Availability: Limited and irregular, requiring drought tolerance.
-
Exposure: High UV radiation and wind that increase evaporation.
What to Plant by Dry, Hot Site Type

Site Type |
Best Plant Choices |
Why These Work |
|
Dry hills and slopes |
Kunzea ericoides (Kānuka), Leptospermum scoparium (Mānuka), Ozothamnus leptophyllus (Tauhinu), Coprosma Red Rock |
Hardy shrubs that tolerate drought and poor soils, with small, tough leaves that reduce water loss. |
|
Rocky outcrops & ridges |
Poa cita (Silver tussock), Leptospermum scoparium (Manuka), Olearia paniculata |
Plants adapted to shallow soils and heat, with deep roots and spiny or small foliage to reduce moisture loss. |
|
Dry river terraces & plains |
Austroderia richardii (Toetoe), Coprosma propinqua, Olearia odorata, Astelia Westland; Coprosma ‘Hāwera’ |
Tough grasses and shrubs that survive dry conditions and provide shelter. |
Signature Dry, Hot Native Plants
-
Astelia Westland – Strong architectural clumping plant; “withstanding most conditions including dry, cold & wind.” Good for contrast and tough spots.
-
Leptospermum scoparium (Mānuka) – Hardy shrub with fragrant foliage, drought adapted.
-
Ozothamnus leptophyllus (Tauhinu) – Light, silvery shrub well-suited to dry soils.
-
Poa cita (Silver tussock) – Deep-rooted tussock grass thriving in dry, exposed areas.
-
Coprosma Red Rock – Groundcover/divaricating shrub with small needle‑like foliage; good in hot, dry conditions; good for banks or underplanting.
Planting Tips for Dry, Hot Sites

Tip |
Advice |
|
Planting time |
Early autumn or late winter to establish before hot, dry summer conditions. |
|
Soil preparation |
Incorporate organic matter if possible to improve moisture retention in poor soils. |
|
Watering |
Water regularly during establishment, then reduce frequency as plants mature and root deeply. |
|
Mulching |
Use coarse mulch to conserve soil moisture and protect roots from heat stress. |
|
Shelter |
Protect young plants from harsh winds with temporary shading or windbreaks if needed. |
