Here, Chris Bonnett from GardeningExpress has shared his favourite plants and flowers for unpredictable UK summers. 

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 most robust and adaptable varieties will be capable of handling both drought and waterlogging. 

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

Geraniums

Geraniums are incredibly hardy and can tolerate a wide range of conditions. They thrive in full sun to partial shade and are drought-resistant once established, making them ideal for the hot spells. They can also cope with wet conditions without succumbing to rot. 

Regular deadheading will encourage continuous blooms. Take care to ensure good drainage if planted in pots.

Lavender

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.

Black-Eyed Susan (Rudbeckias)

Black-Eyed Susan, or Rudbeckias, are resilient perennials that flourish in a variety of soil types. They are particularly good at withstanding heavy rain and waterlogged conditions, as well as temporary periods of drought. Their bright, cheerful flowers bring bursts of colour to any garden. 

Plant in a sunny spot for best results and deadhead spent flowers to prolong the blooming period.

Sedum (Stonecrop)

Sedums are succulent plants that store water in their leaves, making them exceptionally drought-tolerant. They are, however, also tough enough to handle wet conditions. Sedums are low-maintenance and can thrive in poor soil, making them versatile garden additions and great for gardeners that aren’t particularly green-fingered. 

Plant in a sunny or partially shaded location and ensure soil is well-drained to prevent root rot.

Hostas

Hostas are shade-loving plants that can tolerate a wide range of weather conditions. They are particularly resilient during wet spells but can also survive drier periods if they have some shade and moisture. 

Make sure you protect hostas from slugs and snails, which can be a problem in damp conditions. Regular watering during dry spells will help maintain their lush green leaves.

Salvias

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.
