Summer tests a garden. Long dry stretches, intense afternoon sun, and the occasional heatwave separate the plants that earn their place from those that merely fill space.
The right selections hold their form, colour and structure through the season’s harshest months, without demanding constant intervention. Here are the varieties we return to again and again for gardens that need their plants to thrive through summer.
Lagerstroemia ‘Natchez’
Lagerstroemia ‘Natchez‘, or Crepe Myrtle, earns its place as a focal point tree. Smooth, rich brown bark peels away in strips, while clusters of ruffled white flowers bloom at the branch tips through mid-to-late summer. Dark green foliage carries through the warmer months before turning shades of orange and red as autumn sets in.
Planted in full sun with well-drained soil and watered regularly while establishing, it grows to 7–9 metres tall. Well suited to anchoring a front garden or framing an entry.
Once established, it’s drought- and heat-tolerant, and pruning is best done in winter or early spring, since blooms form on new wood.
Poa labillardieri ‘Eskdale’
Poa labillardieri ‘Eskdale’, or Tussock Grass, brings finely textured, blue-green foliage that flowers with feathery seed heads through summer. Its upright, arching form softens hard surfaces such as paving, and when mass planted it creates a wild, windswept quality in the garden – a treatment we’ve used to flank a bluestone and filetti path in our Hawthorn Rose project.
It tolerates almost any soil type, establishes quickly, and is drought tolerant once settled in, asking only for a cutback through late winter and a feed of slow-release fertiliser to encourage fresh growth.
Pratia pedunculata
Pratia pedunculata, commonly known as White Star Creeper, is a fast-growing, evergreen groundcover that forms dense mats of foliage, dotted with delicate white flowers through spring and summer. It thrives between stepping stones, alongside pavers, or as a border along garden beds, and copes well with light foot traffic where you want a soft lawn alternative.
In sun to part shade and well-drained soil, it establishes quickly – quickly enough that it warrants monitoring to keep it within bounds. Regular summer watering keeps the soil moist and the foliage lush through the hottest months.
Salvia guaranitica
Salvia guaranitica, commonly known as ‘Purple and Bloom’, is among the hardiest performers in this list, adaptable across most Australian climates and equally at home in a garden bed or large container. Its mounding, deep green foliage carries dark purple blooms from spring through autumn, drawing bees, butterflies and birds throughout the warmer months.
Once established, it tolerates drought, frost, heat and humidity with minimal watering, needing extra attention only through extended dry spells. It’s a plant that rewards a single season of care with years of reliable colour.
