Drought tolerant plants

With the current challenging conditions that gardeners face, it may be time to consider changing plants to cope with the climate change.
Considerations: Use plants with silver or grey-green leaves, as these reflect the sun’s harsh rays. Plant smaller specimens so they can adapt to the growing conditions. Mulch with bark to help retain water in the soil.

1. Passiflora caerula
Passion flower roots should be encouraged to go deep into the ground, so water deeply but infrequently. This helps the plant become drought-tolerant as the roots are powerful enough to source water.
Ideal on a sunny south-facing wall, Passion Flowers will bloom during the hot summer months. Long, twisting tendrils will climb up to 30ft. Flowers can be in shades of blue and white and some are fragrant.

2. Stipa gigantea
These are low maintenance, architectural plants that produce arching stems up to 7ft tall with oat-like flowers, which fade to gold. These plants will add height and movement to a mixed border most of the year, as the flowers can be left on the plant throughout the winter to add interest.
This is plant that is used to drought as it is native to the Mediterranean. It’s commonly used in Prairie planting and in savanna habitats.

3. Salvia
Woody, shrub varieties such as Silas Dyson, Javier and Sierra San Antonio are extremely drought tolerant and hardy through most winters in free-draining soil. Others such varieties like Salvia Argentea have silver, woolly like foliage to trap moisture on the leaf surface.
Flowers are produced for weeks throughout late spring until late summer and are a magnet for bees and butterflies. Remove flower spikes to encourage further blooms.

4. Eryngium
Originating from south America, this plant can’t get enough of the sun. It can be grown in a mixed sunny border or even in a gravel bed.
This plant has unusual marbled foliage with spikey vivid blue flowers in late spring and summer. A favourite for florists.

5. Cordyline australis
Native to New Zealand, this palm is popular across the UK as it can be grown outside year-round, with protection in the winter. It is also tolerant of wind and coastal exposure.
It required only minimal water, even when a prolonged dry spell is occurring and is an ideal focal point in an exotic border or on the patio. Arching, light green leaves are retained all year and once established, fragrant white flower spikes are produced.

6. Olearia macrodonta
Commonly known as the New Zealand Holly, this plant has holly-like leaves that have a silver felted texture beneath which helps attract moisture out of the air.
Small, fragrant clusters of white flowers are produced over the summer months. Thieving best on shallow chalk soils, this is a vigorous grower, which will tolerate hard pruning.
