Summer and autumn colour

The non-veg side of things in the garden needs a bit of attention as there isn't a huge amount of colour at the moment. I'm currently scouring the August edition of Gardener's World to get some ideas for new plants but in the meantime, I've found this thread on the Grapevine forum too. Here's a list of recommended plants for summer and autumn colour:

Rudbeckia (an orange one would be good; long lasting)
Love Lies Bleeding (long red tassles; long lasting)
Dahlia (flower until first frosts)
Crocosmia (flowers late summer)
Sidalcea (flowers late and lasts a long time)
Asters (come really late)

Summer into autumn colour - perennials:

Achillea
Echinacea
Helenium
Salvia
Cosmos
Sedum
Lavender
Penstemon
Scabious

Looks like it's off to the garden centre this weekend to see what they've got!
