As we experience an ever changing climate we’re beginning to accept longer, hotter summers as the norm. While we may enjoy topping up the tan in the sunshine, these higher temperatures bring with them a range of challenges for gardeners. The biggest of which is the lack of water and the impact this has on parched plants. Whole swathes of much loved and carefully tended areas of our gardens can be severely damaged by baking in the sun, without sufficient water.
Improving water collection and irrigation is one way to help deal with dry conditions. The other is to rethink our plant choices. By swapping water hungry plants with drought tolerant varieties we can ensure displays stay resplendent throughout any heatwaves.
And the great news is drought tolerant doesn’t mean boring. There are hundreds of beautiful plants genetically adapted to surviving dry spells. We’ve picked ten of our favourites known for their drought tolerance.
1. Lavender
Full Name – Lavandula
Foliage – silver-grey or green-grey
Sunlight – Full sun
Soil – Sand, chalk, or loam
Plant Colour – Blue, purple, pink and white
Known for its aromatic fragrance and beautiful purple blooms, lavender is an excellent choice for drought-tolerant gardens. Naturally adapted to arid conditions, lavender stores water in its stems, leaves and deep root system. So once established it can thrive in hot, dry conditions, requiring minimal watering and low maintenance. Its fragrant flowers also make it especially attractive to beneficial pollinators like bees and butterflies, so also suits a wildlife garden situation.
Lavenders are easy to grow and associate well with other shrubs, perennial plants and roses. For long-lived, hardy varieties, choose English lavender cultivars (Lavandula angustifolia and L. × intermedia). Other lavenders, such as French lavender (Lavandula stoechas), are slightly less hardy so may need replacing every few years.
