My old favourite Crocosmia ‘Lucifer’ again, this time in a border* (not my garden). I think it looks amazing: such a fiery, blazing red, which works well against the cool and neutral colours nearby.
And here are two more ideas for colourful borders. Unfortunately, I don’t know the names of all the plants, although I think one of them is similar to Crocosmia ‘Lucifer’, but here goes!
* I’ve included the top picture twice because I’m experimenting with a new theme: you have to roll over the featured image to see the colour. I like the idea, but didn’t want that glorious red to go unnoticed by anyone. I’d really welcome comments on whether the new theme suits my blog.
