What flowers to plant next year for hot weather?

I have spent to long and to much money in water bills watering this year and I wondered if anyone would care to offer a list of plants that survive in the sort of hot weather we have been having in England.

 

Are you looking for perennials or half hardy/hardy annuals?
Also there is a difference between survive and flourish,although there are perennials that will do pretty well in dry conditions once established

 

Sedum, euphorbia, thyme, rosemary, lamb's ear plant, coton lavender, curry plant, lavender....

 

Perennials or half hardy/hardy annuals? Whatever is prety and will survive in a hot season with minimum watering,
Many thanks for all your answers.

 

Most half hardy bedding plants need water, I think you need to look at establishing perennial plants that can basically look after themselves once established.
Having said that you need to remember they all have their flowering periods so many may not look at their best all the summer.

 

A lot of the herbs would fit the bill.
Sage has lovely foliage, there are various leaf variations, and it has the bonus of wildlife-friendly flowers.
Savoury is a good do-er, and will readily give good ground coverage. I find on my poor dry, sandy soil, it establishes and thrives more effectively than thyme. It has a short, brief spell of pure white flowers that the bees love, but looks good all year round.
Various thymes - there must be one or two that float your boat!
Rosemary does well, and can be shaped/cut back. The new foliage is gloriously lush.
Marjoram is good, and will flourish in poor conditions.
Rocket copes with dry weather, and will tell you when the other plants need a drink.
All of the above have the added advantage of tasting good too!

lychnis coronaria does well in dry conditions, nigella does too. Aquilegia tends to flourish and die back before the drought hits too hard.

Lavenders, once established, will do well.
