What are your favourite plants for a herbaceous border?

[DarkBlueEyes]

I have got a new plan for my new garden ridiculously excited. I have a herbaceous border to plan.

I've got lots of ideas but want to tap into your collective wisdom. I'd like blue, purple and white plants and want to think about how it will look over winter.

What are your favourites? I'm in Surrey if that helps in terms of climate/frost sensitivity etc.

Thank you :)

Euphorbias and sedums. Big, easy, low maintenance, slug-proof. Good for mid-back borders as a foil to the flashier/flowerier stuff. Sedums are especially handy for autumn colour/butterflies.

Hebe and cranesbill geraniums both come in purple and white, large and small. Flowering over winter might be a problem, but Hebe varieties have lovely coloured leaves all year round.

I love hebes. I'm kiwi. ;). Geraniums also a great idea I love johnsons blue. Keep them coming!

I've just done an entire border in purples, whites and greens.

Perovskia, salvia, hebes, convolvulus, parahebes, box, euonymus, jasmine, iceberg rose, Japanese anemones, glauca festucca (I think), purple clematis, Polish something and a hydrangea bobo. Just looking for the perfect purple hydrangea to finish it off.

campanulas are good too, different sizes and habits.

My MILhas an lovely plant called Honesty in her garden. To me it looks like Dame's Rocket, lilac coloured, and also these gorgeous translucent seed heads come on over the winter.

Look for some of the lavender and purple coloured penstemons. They're pretty well evergreen throughout a mild winter and the flower spikes are loved by bees.

Echinops. Persicaria - the tall dark pink one is a magnet for bees. Geranium psilostmon bright magenta pink. Autocorrect is making this a nightmare to type.

I love penstemons, they are so on the list! Thanks, I have some nice ideas and now have this list to choose from:
Salvia
alchemilla mollis
delphiniums
alliums
ceratostinum willmottianum excuse spelling
daphne (white)
paeonies
lithospermum
lupins
agapanthus (can divide some I already have)
anchusa
campanula
viburnum bookwoodii
roses
liles
penstemons
geraniums
small hebe
perovskia

That may well be enough, but you never know!
