Favourite hardy perennials

[Grockle]

What do you love?

I'm going to the garden centre and need a list

What type of garden have u got is it shady, full sun etc. You can get plants for most aspects so in choosing your plants it's best to consider where they are going to go. If you want to post some details of you garden that would help with suggesting the type of plants that would be suitable.

North facing but sunny most of the day. Well drained soil, probably acidic (heathland and blueberries grow round here)

I'd love lots of pretty flowers to attract bees & butterflies.

I have lots of lavender, lilac trees & snowberries (nightmare)
