When the temperature soars and Sydney sizzles, your hydrangeas might flop, but many favourite old garden plants soldier on without a hint of stress, providing dazzling colour and perfume.

Mostly fallen from fashion, these old garden varieties were the mainstay of many early Australian gardens, often brought from other parts of the world with similarly warm and humid climates. Hot weather seems to bring out their best qualities as they provide a succession of flowers and ornamental foliage withstanding the hottest driest days.

On New Year’s Day, I took a stroll around the garden at Vaucluse House to capture a few of these old stalwarts in full flower. Here are some of my highlights.

Cultural note:

At this time of year attention to mulching and careful watering will ensure your favourite plants survive the hottest days. An organic mulch covering the soil surface will reduce evaporation ensuring plant roots are kept cooler and able to find soil moisture. It is important not to over-water as this makes plants weaker and more dependent on frequent watering. You can easily condition your plants to survive harsher weather by watering deeply but less often. Most of the plants in this article will happily get by with little or no supplementary watering at all which makes them all the more desirable!
