Plant experts from GardeningExpress have shared their favourite flowers that can thrive come rain or shine, including geraniums, lavender and hostas.

Chris Bonnett from the company said: “Summer weather in the UK has always been a bit unpredictable, but this is only set to worsen as the effects of climate intensify around the world.

“Gone are the days when we could rely on consistent weather patterns. Instead, we now face an erratic mix of heatwaves, torrential downpours, and cool, breezy spells, represented perfectly in the last few weeks alone.

“For garden enthusiasts, this presents both a challenge and an opportunity. Inconsistent weather can be stressful for plants, and only the more robust and adaptable varieties will be capable of handling both drought and waterlogging.

“Therefore, selecting plants that can thrive no matter the weather is key to maintaining a beautiful and resilient garden.”

1. Geraniums

Geraniums are “incredibly hardy” and can tolerate a range of conditions, including full sun and partial shade.

They are drought-resistant once established, but can also cope with wet conditions without succumbing to rot.

Make sure to use regular deadhead geraniums to encourage continuous blooms, taking care to ensure good drainage.

2. Lavender

The expert said: “Lavender is a Mediterranean native well-known for its drought tolerance and ability to thrive in full sun, making it perfect for the hotter, drier periods of a UK summer. Its fragrant flowers also attract pollinators, adding to the ecological value of your garden. 

“Plant lavender in well-drained soil and avoid overwatering. Prune annually at the beginning of autumn to maintain shape and encourage new growth.”

3. Hostas

Hostas are shade-loving plants but can tolerate a wide range of weather conditions, ideal for wet spells and hot summer spells.

Make sure to protect hostas from slugs and snails, which can be a problem in damp conditions.

The gardening expert recommended regular watering during dry spells to help maintain their lush green leaves.

4. Salvias

The pro continued: “Salvias are a diverse group of plants known for their vibrant flower spikes and aromatic foliage. They are drought-tolerant and thrive in sunny conditions, making them perfect for hot, dry spells. Many varieties of salvia are also resistant to pests and diseases, adding to their resilience.

Plant salvias in well-drained soil and full sun. They benefit from regular deadheading to encourage continuous blooming. Pruning in late autumn or early spring will help maintain a bushy, healthy shape. Mulching around the plants can help retain moisture during dry periods.
